Coating particles or granules of urea with sulphur and a sealant results in the formation of a membrane that regulates the availability of nitrogen for plant growth.Sulphur Coated Urea (SCU) fertilizer is a slow-release fertilizer that is made by coating urea with sulphur and wax that increases nitrogen efficiency, improves plant growth and reduces water pollution, compared with water soluble fast-release urea. Sulphur Coated Urea Avoid soil compaction; reduce frequency of application and reducing total cost; effectively reduce salt index, improving quality of crops; sulphur is a middle element, to provide nutrition for crops. As a hi-tech controlled/slow release fertilizer, Sulphur coated urea (SCU) has both effects of nitrogen and sulphur fertilizers.

Business Plan- NPK Fertilizer & Calcium Ammonium Nitrate (CAN). Growing Industry to Start a Business.
Ammonium nitrate (AN) is one among the foremost common commercially available nitrogen fertilizers, the content of nitrogen during which amounts up to 35% by mass. The most agrochemical advantage of a compared to other simple nitrogen fertilizers is to present nitrogen both in ammonia and nitrate forms. Herewith, the high content of this component enables to combine it with other varieties of fertilizers and acquire complex fertilizer with the high content of basic nutrients—nitrogen, phosphorus and potassium. The most disadvantages of such sorts of fertilizers are their high hygroscopicity, caking and therefore the increased requirements for fire and explosion safety.

Fertilizer is a material that is added to the soil to supply one or more elements required for plant growth and productiveness. Plants need to be fertilized because most soil does not provide the essential nutrients required for optimum growth.
The three numbers on fertilizer represents the value of the three macro-nutrients used by plants. These macro-nutrients are nitrogen (N), phosphorus (P) and potassium (K) or NPK for short. All plants need nitrogen, phosphorus and potassium to grow. Without enough of any one of these nutrients, a plant will fail. An NPK fertilizer provides those three nutrients in ratios particular to the plant being grown.

This is my slide which was done when i was in Level 3, Semester 2. This slide is based on our Industrial tour to Triple Super Complex Limited, Patenga, Chittagong, Bangladesh.
This book covers design of high Pressure equipment and developments, Process flow diagram of different section of Ammonia, Urea and others fertilizers .Fundamentals of ammonia urea plant trouble shooting risk assessment corrosion in different vessels and remedies. This book is useful for Engineers and Sr. Managers for plant commissioning and trouble shooting and Engineering Students. This book contains about 51 tables and 144 useful diagram and chart graphics etc. Detail description of ammonia/CO2 stripping process and new developments. Design Parameters of High pressure vessel and comparison. Study of corrosion for various equipments and control. How to control corrosion by changing of equipments material.
This is a precise presentation on NPK fertilizers or complex fertilizers. It has detailed flowsheets with descriptions about all manufacturing processes of NPK fertilizers as well
Classification of chemical fertilizers • organic fertilizer and inorganic fertilizer • Sources of Organic fertilizers • Inorganic fertilizers • Nitrogenous fertilizers • Phosphate fertilizers • Potassic fertilizers • Secondary major-nutrient fertilizers • Micronutrient Fertilizers • On the base of physiological effect • On the basis of physical forms • Granular fertilizers
Control release fertilizers are coated fertilizers that release nutrients over an extended period of time at a rate driven primarily by temperature and moisture of the root zone. It has been estimated that slow-release fertilizers comprise only 8-10% of the total fertilizers used in Europe, 1% in the USA and only 0.25% in the World. Dong and Wang (2007) reported that in Japan 70% of polymer coated controlled-release fertilizers are used in rice. Polymer coated fertilizers are a type of control release fertilizers, which are solid or other nutrient core, coated with various polymers. Fertilizer use efficiency can be increased by application of polymer coated fertilizer compared to common fertilizers due to very less nutrient losses. Most common three marketed products are Nutricote, Osmocote and Polyon. Pawel (2013) found that the polymer-coated fertilizers are not straight nitrogen but NPK fertilizers, particularly when containing secondary and micronutrients, the rate of release of the different nutrients, N, P, K, S, Ca, Mg and micronutrients, are generally slow, controlled-release and stabilized fertilizers not stated. Parvathi (2018) reported that customised fertilizers are multi- nutrient carriers facilitating the application of the complete range of plant nutrients in right proportion to suit the specific requirements of a crop during its stages of growth.
Nelson et al. (2012) reported that application of nitrogen @ 120 kg/ha by polymer coated urea (PCU) with non coated urea (NCU) in the ratio of 75:25(PCU:NCU) recorded the highest wheat grain yield (5370 kg/ha) and lowest with ammonium nitrate (5110 kg/ha). Dong and Wang (2007) reported that application of polymer coated nitrogen fertilizer recorded the highest Nitrogen Use Efficiency (70.54%), Nitrogen Agronomic Efficiency (32.56 kg/ha) and Nitrogen Physiological efficiency (46.16 kg/ha) compared to uncoated common fertilizers in rice crop. Prasad et al. (2012) reported that application of nano zinc fertilizers showed significantly better results in germination, shoot and root growth and Seed vigour Index over common zinc sulphate and control treatment. They also reported that application of NPK+ZnO (Nano) @2g/15 l resulted the highest plant height (43.80 cm), no. of pods per plant (16.80) and no. of filled pods per plant (15) which were significantly superior over rest of the treatments in groundnut crop.
It can be concluded that application of polymer coated fertilizers increase the Nutrient Use Efficiency (NUE), Nitrogen Agronomic Efficiency and Nitrogen Physiological efficiency, they increase the % recovery of nutrients and finally the growth and yield of crops. Nano-fertilizer certainly has the potential to improve agriculture production and they release the fertilizer slowly and extend the fertilizer effective period resulted in higher crop yields. Use of Customized Fertilizers can maximize nutrient use efficiency and ultimately improve soil fertility.

In Prilling Tower the ambient air is used as the cooling air stream for this process. In hot days, the temperature of the product at the bottom of the tower are hot that cannot be packed directly.Prilling tower have variable opening louvers system, this helps to control air intake flow to prilling tower at bottom, which is very useful in rainy seasons as CRH (critical relative humidity) of urea becomes less than atmospheric humidity and prills tends to absorb moisture from air. Humidity of air along the height of tower increases due to evaporation of moisture from prills. Rate of change of humidity at the top is more than that at the bottom indicates most of the moisture is removed at the top when the prills is in the liquid stage. In addition, in hot/ humid days, the prills form lamps and cakes with each other. To overcome this problem the bulk flow cooler (BFC) or cooling fluidized dryer (CFD) are used.
A mathematical hydrodynamics, heat, and mass transfer between the urea and the cooling air is developed. The prilling tower is the source of pollution in form of dust and ammonia and that can be control by simple technic also energy saving in terms of ammonia saving, ammonia is the harmful pollutant if you vent and useful product if you recovers.

Advancement in neem oil extraction process Prem Baboo
This paper describes a process of preparation of neem oil water emulsion & coating of urea in fertilizer plants, at site of urea production. The neem tree found in Asia and basically Indian sub continent. The basic part for neem oil used is seed of the neem known as kernels .Different method are available to obtain neem oil including one new method Supercritical method for extraction of neem oil from kernels.Now a days the main demand of neem oil in fertilizers Industries for coating of Urea and other fertilizers. “Government of India has done away with the cap on neem- coated urea and now it can be produced 100%. It is a win-win situation for both industry and farmers. It has been noted that farmer’s income would increase with the help of neem-coated urea as productivity would increase with less usage of urea.”Consequently the demand of Neem oil drastically increasing. In this paper some description of oil preparation method. Using carbon dioxide: methanol for supercritical fluid extraction is the maximum yield eco friendly process but slightly economical.
Latest steps taken to control air pollution Prem Baboo
There has been a "seven-fold increase" in Delhi's air pollution level since October 2015,
a Center for Science and Environment (CSE) expert said today even as real-time
exposure readings of nearly all monitoring stations put PM 2.5 and PM 10 figures above
the 'severe' threshold. Growing population of the city.
A case study of thinning of ng (natural gas) injection line in mp section bef...Prem Baboo
In urea plant Medium pressure Inerts gases recover HRU burner in Captive Power Plant. The inserts containing useful fuel in the form of Hydrogen & Methane about 40-45% volume percentage of total inerts. This inerts also containing Oxygen because the passivation air is given in carbon Dioxide compressor suction line for passivation of Reactor vessel and all downstream Stainless Steel vessel. In the presence of Oxygen there are chances of explosive mixture of Hydrogen and Oxygen in exit of MP section final vent line, to overcome this dangerous situation natural gases are added in the MP section before MP condenser so that the range of explosive can be avoided. These gases Hydrogen & Methane come with carbon Dioxide gas from Ammonia plant, carbon Dioxide about 0.5-0.7 % and Methane about 0.08 to0.1%. But we have seen after implementation of this scheme, frequent leakage was observed from inlet flange as well as heavy erosion was noticed in the inside surface of vapour inlet line and flange. Erosion was noticed from NG injection point and extended downstream up to nozzle flange in elliptical pattern. Material of construction of the process piping is A312 TP -316 L (Cr-18%, Ni-12%, Mo-2.0%, N-0.2%, and C-0.03%) which is compliable as per basic licenser. Hence frequent thinning of the pipe wall nearing injection point is due to sudden expansion of natural gas. In order to minimize pipe wall erosion phenomenon near NG injection point an alternative arrangement of NG injection extending the 1” NG line up to center of the vapour inlet line has been implemented and location of injection also changed as fig.-3.
Hydrogen recovery from purge gas(energy saving)Prem Baboo
Ammonia is continuously condensed out of the loop and fresh synthesis gas is added. Because the synthesis gas contains small quantities of methane and argon, these impurities build up in the loop and must be continuously purged to prevent them from exceeding a certain concentration. Although this purge stream can be used to supplement reformer fuel gas, it contains valuable hydrogen which is lost from the ammonia synthesis loop In order to achieve optimum conversion in synthesis convertor, it is necessary to purge a certain quantity of gas from synthesis loop so as to as to reduce inerts concentration in the loop. Purge gas stream from ammonia process contains ammonia, hydrogen, nitrogen and other inert gases. Among them, ammonia itself is the valuable product lost with the purge stream. Moreover it has a serious adverse effect on the environment.This purge gas containing about 60% Hydrogen was fully utilised as primary reformer fuel.
Energy saving in urea plant by modification in heat exchanger and processPrem Baboo
Energy is the prime mover of economic growth and is vital to the sustenance of a modern economy. Improvement in energy
efficiency reduces cost of production & results in environmental benefits, e.g. mitigation of global warming by way of less emission of
Green house gases in the atmosphere. Over the years several energy conservation measures have been taken towards reduction in
specific energy consumption and improvement in energy efficiency. The efforts’ resulted in reduction in specific energy consumption
from 6.27G. Cal/tone of Urea to 5.421 G.Cal/tone of Urea in 2015-16 as shown in the Graph No 1 & 2 with energy & down time.
Further a major modification of all plants is under way. Most of the schemes have been implemented in 2012 and the further
modifications expected to result again reduction of energy consumption for ammonia and Urea plants. This paper described some of
the modification in urea plants implemented recently in May/June 2016.
Cause and prevention for steam turbine blade scaling & fouling Prem Baboo
The paper intended to deposition of Wang scaling/deposition & corrosion on turbine blades. How to deposit these scales? Prevention and control the deposits. Major steam turbine problems causes and effects. Practical examples of our shut down experience of 40 ata & 100 ata steam turbines. Lab analysis detail report of wet steam cleaning and sand blasting cleaning of the blades.

The paper intended to the standpoint of harmful emissions typical nitrogen-based fertilizer plants producing ammonia and urea plants using the advanced available technologies. The critical emission points are established and analyzed. Several possible actions have been taken in order to minimize the emissions are presented.The method is low cost and at the same time enhances the fertilizer value of sewage sludge. It therefore has a large potential of competing with more established methods of sanitization.
Fertilizer Coating Materials Increase Fertilizer Efficiency In AgricultureNAQ Global
To enhance crop productivity, slow-controlled release fertilizers are used that can increase nutrient use efficiency and lower the negative impact on the environment. Slow controlled-release fertilizers reduce nutrient loss, increase crop production, and reduce plant toxicity and stress. A wide range of fertilizer coating materials that is applied to granular or prilled nitrogen fertilizers.

Full paper gives how Rotoform process can meet the expectations of enhansed fertilizersizers. Deatilled scheme and process is explained. A case story is also explained based on the recent order from Zaklady Azotowe Pulawy S.A
Ever since the declaration of 100% neem coated urea by India Government, the number of neem trees is increasing continuously in India Neem coated urea requires neem oil, more urea more oil and trees also required more. When it comes to oil, neem plants are rather promising. Probably no other plant yields as many exploitable by-products and benefits. Earlier, 100% Neem Coated Urea was made mandatory in 2015.

Our plant temperature of prills is also 65-700C.This result in poor strength dust formation, increase in caking tendency. Granulated urea has definite advantage over prilled urea but expensive to produce till recently. We have installed BFC for line-1 & 2.A modification also done in Urea line –I plant in month of March 2018 to solve foaming problem in waste water section (distillation tower) and this modification proven and beneficial.
Identification and Selection of the Best Industrial Wastewater Treatment Tech...theijes
A bench scale model and treatability study was developed for chemical product “detergents, shampoos, toilet soaps and sanitary paper” industry to study the analysis of waste discharge. The main process lines used in the industry are fabric and home care production unit, soap production unit, and sanitary paper production unit. The main environmental problem of the industry is that the industrial wastewater resulting from the facility is not meeting the limits of the environmental regulations for the discharge of wastewater to the sewer network. Accordingly, the industry has to treat the wastewater prior to its discharge to the wastewater sanitary network. The main objectives of this study are management and control of liquid and solid wastes in the industry as well as selecting the different possible treatment trains for the waste water prior to its discharge to the sewer system in order to protect the environment and to gain benefits as much as possible from the wasted materials and identify opportunities for introducing pollution prevention measures and best method for waste minimization as cleaner production system. The study is taking into account all types of waste production including wastewater and solid waste during the production processes activities. Treatment Procedure is conducted through treatability study using two proposed streams of techniques; biological treatment technique (Anaerobic Treatment) and chemical treatment followed by biological treatment technique (Coagulation followed by Sedimentation). According to the different treatment alternatives conducted through the study, it is proved the biological method is not suitable for this type of waste, as the antifoaming chemicals and enzymes present in the wastewater leads to death of the microorganisms and accordingly the failure of the treatment system. As for the chemical treatment, it provided good results in both industrial wastewater mixed with domestic wastewater, and industrial wastewater alone. It also provided good results when using both ferric chloride and aluminum sulphate. It is concluded that the coagulation and Flocculation process followed by plain sedimentation is the most reliable alternative treatment method for this kind of industry using ferric chloride for the wastewater without domestic wastewater. The removal efficiency reached 72 to 79%, 86 to 96%, 83 to 88% and 86% for COD, TSS, Phosphorous, and Oil and Grease respectively.
The explosion hazard in urea process (1)Prem Baboo
In Urea plant passivation air is used in reactor, stripper and downstream of the all equipments. The reactor liner material used Titanium, Zirconium, SS 316L (urea grade), 2RE-69 and duplex material .except Titanium and Zirconium all stainless steel required more passivation air. In CO2 some quantity of Hydrogen is present about 0.14% to 0.2% . The passivation oxygen and Hydrogen makes explosive mixture. To avoid a fire or explosion in a process vessel is to introduce inert (noncombustible) gases in such a way that there is never a mixture with a combustible concentration in exit of MP vent. Mixtures of fuel, oxygen, and inert gases are not combustible over the entire range of composition. In CO2 stripping process the HP scrubber is the risky vessel and this vessel consisting blanketing sphere, Heat exchanger part and a scrubbing part. With help of triangular diagram that shows the shape of the combustible/noncombustible regions for a typical gaseous mixture of fuel, oxygen, and inert at specified temperature and pressure. Present article how to avoid that combustible rang and how to tackle that gases in CO2 & ammonia stripping process.
Over the past two decades, the ammonia and urea industry have witnessed spectacular metallurgical developments for process equipment. For example, stainless steels, modified with special materials, can improve high temperature creep rupture resistance. Using duplex stainless steels and modern corrosion abatement techniques are other methods that improve plant-operating performance.
Prills /granular urea are not only costly for the producer but may be harmful to humans and the environment. Furthermore, nano Urea may also be used for enhancing abiotic stress tolerance. Nano-Urea prevents environmental pollution and improves physiological traits of wheat grown under drought stress conditions. The nano urea consist of higher surface area because lesser in size of the nano particle and have high reactivity, solubility in water. Nano Urea are the important tools in agriculture to improve crop efficiency, yield and quality parameters with increase nutrient use efficiency, reduce wastage of fertilizers and cost of cultivation. Nano-urea is very effective for precise nutrient management in precision agriculture with matching the crop growth stage for nutrient and may provide nutrient throughout the crop growth period. Nano-Urea increase crop growth up to optimum concentrations further increase in concentration may inhibit the crop growth due to the toxicity of nutrient. Nano-Urea provide more surface area for different metabolic reactions in the plant which increase rate of photosynthesis and produce more dry matter and yield of the crop. It is also prevent plant from different biotic and abiotic stress.
Installation of S-50 ammonia synthesis converter along with waste heat boiler in downstream of existing S-200 ammonia synthesis converter is one of the major schemes of Energy Saving Project of Ammonia plant. The energy saving reported 0.18 G.Cal/T of Ammonia. Several ammonia plants have installed an additional ammonia synthesis converter in combination with a HP steam waste heat boiler, downstream of the existing ammonia converter. The result is increased conversion per pass, reduced compression requirements due to the smaller recycle gas stream, and improved waste heat recovery. Among the methodologies aimed at finding energy saving opportunities, pinch analysis linked to power and steam modeling has proved to be a powerful way for determining projects to improve the overall energy efficiency of industrial sites. This procedure has been applied successfully in many industrial facilities, allowing optimal energy recovery in the process and hence reduction of fuel consumption.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

2. SULPHUR COATED UREA
Author
Prem Baboo
Sr. Manager (Prod)
National Fertilizers Ltd. Vijaipur, India
Abstract
Coating particles or granules of urea with sulphur and a sealant results in the formation
of a membrane that regulates the availability of nitrogen for plant growth.Sulphur
Coated Urea (SCU) fertilizer is a slow-release fertilizer that is made by coating urea with
sulphur and wax that increases nitrogen efficiency, improves plant growth and reduces
water pollution, compared with water soluble fast-release urea. Sulphur Coated Urea
Avoid soil compaction; reduce frequency of application and reducing total cost;
effectively reduce salt index, improving quality of crops; sulphur is a middle element, to
provide nutrition for crops. As a hi-tech controlled/slow release fertilizer, Sulphur
coated urea (SCU) has both effects of nitrogen and sulphur fertilizers.
Introduction
Urea is used extensively as a high Nitrogen fertilizers but agronomic test have shown
that 15-70 % of the applied urea may be lost due to leaching and could therefore be
unavailable to crops.There has been exponential growth in the earth's population that
has now reached approximately 7.4 billion and approach 9.52 billion by 2050. Global
food requirements have also risen and the expected per capita food requirement is
likely to double by 2050. Meanwhile, arable lands diminish due to industrialization,
urbanization, and desertification and land degradation from heavy flooding. These
3. intimidating factors threaten global food security and demand a robust response.
Multidimensional steps have already been taken worldwide to meet the challenge of
food security with modifications to improve agricultural systems. To meet the
increasing food demands, the agricultural sector is bound to employ enormous
quantities of fertilizers that have thus far demonstrated undesirable environmental
impacts. Hence, it is of paramount importance to develop systems that boost production
and alleviate environmental problems. Controlled Release fertilizers may be one such
solution as they are believed to enhance crop yield while reducing the environmental
pollution caused by the hazardous emissions (NH3, N2O etc.) from current fertilizer
applications .Sulphur coated urea is a controlled release fertiliser produced by coating
hot urea by molten sulphur polyurethane oil or a microcrystalline wax. The ideal ratio
comprises 30%–40% nitrogen and around 20% sulphur. Sulphur coated urea is
specialised fertiliser that is coated with wither wax or polymer and releases nutrients
slowly. Sulphur coated urea finds application predominantly in agriculture, golf courses,
professional lawn care and turf, green houses, horticulture and nurseries. By region, the
global sulphur coated urea market is segmented into North America, Western Europe,
Asia Pacific Excluding Japan (APEJ), Eastern Europe, Latin America, the Middle East and
Africa, China and Japan. Of these, North America is the most prominent markets, both
collectively accounting for over 60% value share of the overall market in 2016.
Drivers & Restraints
Growing concerns over sustainability and cost minimisation in the agriculture sector is
driving demand for sulphur coated urea globally. Stringent regulatory framework on
conventional fertilisers, concerns about Eutrophication, and preferences for spending
on luxury amenities such as household lawns and growing number of golf courses are
some of the key factors supporting growth of the global sulphur coated urea market.
Increasing urbanisation and income levels across the globe (especially in Asian
economies) are anticipated to significantly contribute to the overall demand for sulphur
coated urea in the near future. Conversely, increasing commercialisation and product
innovation in alternative products such as polymer coated urea and higher cost of
sulphur coated urea compared to conventional urea fertilisers are some minor factors
restraining growth of the global sulphur coated urea market.
Sulphur-Coated Urea
The additional labour and equipment required to produce coated fertilizers and the cost
of the coating materials make them much more expensive than conventional N
fertilizers. Due to the simplicity and relatively low cost of using sulphur as a coating
material, sulphur-coated urea has become the most commonly used coated-urea
product.
This fact and the high N content of the product (30% to 40%, depending on the amount
of sulphur applied) have added to its popularity among coated products. In addition, as
4. a generic product, its cost has remained relatively low. The sulphur coating is an
impermeable layer that slowly degrades through microbial, chemical and physical
processes Figure-1. The completeness of the coating determines its effectiveness;
incompletely coated or cracked prills are immediately amenable to dissolution in soil
water and hydrolysis by urease. Because not all granules have complete integrity of
their sulphur coating, some N is quickly made available to the soil solution. In fact, the
"7-day dissolution rate" is routinely as high as 30% and may be as high as 40% to 60%
of the total N content of the product in some cases. With such high rates of dissolution, a
rapid initial effect on the crop would be expected.
Fig. No.1
The figure No 2 shows the sulphur coated urea is slow release of Nitrogen.
5. Fig. No.-2
Sulphur + Polymer-Coated Urea
To help solve the problem of irregular nutrient release from sulphur-coated urea, a class
of "hybrid" products has been developed. These products include a thin polymer coating
on top of the low-cost sulphur coating. This has the benefits of reducing the overall cost
vs. that of polymer-only products, while providing a better seal than the sulfur-only
products.
Fig. No. 3
Polymer-coated urea fertilizers use a hydrophobic (water insoluble) coating that
temporarily isolates the urea prill from the soil environment. These polymer coatings
6. may be resins or mineral-based products that act as semi permeable membranes or
impermeable membranes with tiny pores. Nutrient release through these membranes is
controlled by the properties of the coating material, i.e., its permeability characteristics
as affected by temperature and moisture Figure No.-3&4.Thus; they are not significantly
affected by soil properties such as pH, salinity, soil texture, microbial activity, re-dox
potential or cation exchange capacity. Therefore, it is possible to predict and control the
nutrient release rate from these products more accurately than for sulphur-coated urea.

The chemical controlled-release products became available as fertilizers in the many
countries over 50 years ago. From the beginning, their high cost relative to other N
fertilizers has limited their use in large-scale production of commodity crops such as
corn, sorghum, wheat and canola. Rather, they have been more commonly used in
specialty, high-value crops such as vegetables, orchards, nurseries, seed production, etc.
Today, their use is limited but increasing in row crops, primarily due to higher grain
prices, environmental concerns and regulations, and niche uses such as foliar
fertilization. Common classification of urea coating & chemical controlled-release
products are described below in figure No.5.

The fusion of the urea and sulphur is formed in four basic steps.
1. Urea is heated to prepare its surface for sulphur coating.
2. It then enters a rotating drum to be sprayed hydraulically first with
sulphur and then with the wax sealant.
3. The product is cooled, coated with diatomaceous earth conditioner to
prevent caking.
4. Screened and transferred to storage for testing.
The more nitrogen that is fed to and used by turf, the greater its need for sulphur.
Sulphur deficiencies in turf have the same visual signs as nitrogen deficiency; yellowing
of leaves, faint scorching of leaf tip. When used in combination with proper ratios of
nitrogen, phosphorous and potash, sulphur offers the following benefits:
1. Improve water penetration in soil;
2. Increases availability of iron, manganese, copper, zinc and boron to the plant
3. Improves soil structure
8. 4. Builds healthy protoplasm and plant tissue to help resist drought, disease and
winter damage.
5. Enhances colour;
6. Promotes turf growth and density.
7. Aids the turf response when used in combination with nitrogen.
8. Helps keep alkalinity in balance
9. Aids nitrogen release from organic matter.
10. Improves recuperation capacity.
PROCESS DESCRIPTION
The Tennessee Valley Authority (TVA) process developed the first large scale sulphur
coating which was commercialized by Canadian Industries Ltd(CIL).The TVA process
consists essentially of rotary drum into which preheated about 60-750C urea is fed.
Molten Sulphur temperature about 1500C is sprayed onto the urea particles and
solidification rapidly thereby for mixing solid coats. This process consisted of five
stages:
1. The pre heating of urea about 60-750C
2. the coating of the urea particles in a rotary drum, where liquid sulphur
temperature about 1500C was atomized on the particles,
3. A second coating stage with wax to cover imperfections on the sulphur
coating, which presented some holes through which the urea could be
leached,
4. The cooling of the coated product and
5. The adequate conditioning of the product to avoid particle agglomeration.
The process is mechanically complex and the investment and
maintenance costs are high.
Using the spouted bed for coating urea with sulphur. The best quality product is
obtained when the bed is maintaining at 80º C. Evaluating the dissolution rate, D25%,
they concluded that quality increased at higher sulphur mass flow rates and at lower
atomizing air flow rates.
THE UBC SPOUTED BED PROCESS
A sulphur coating process using spouted bed mode was developed by Mathur & Meisen
at the University of British Colombia (UBC) starting 1975. The facilities consisted
mainly of spouted bed i.e. cylindrical column with conical base filled with urea particles.
A high velocity air jet entered the bed from the bottom and carried particles located in
central region of the bed (spout) upwards until they reached the top of the
bed(fountain) whence they fall back into the annulus as shown in the figure No.6.The
annulus behaved as a slowly descending packed bed.

MATERIALS AND METHODS
Elementary sulphur is used as the coating material. Some of its physical properties are
shown in Table -1

Table No-1
When the temperature of the melted sulphur is increased, its viscosity first decreases, as
occurs with most of the liquids, from 17 cp at 120º C to 6.4 cp at 158º C. In this
temperature range the melted sulphur is yellow. Above this temperature viscosity
rapidly increases to a very high value at 160º C, and at this point the melted sulphur is
dark red. This behaviour of the viscosity of sulphur in relation to temperature is
explained by the modification of its molecular structure. The Sauter mean diameter was
obtained by granulo metric analysis in a standard sieve series and is 1.98 mm. A particle
density of 1335.0 kg/m3 is determined.. With these values and the density of the air, we
could verify in following diagram that urea particles are classified as a group D powder,
which justifies the choice of the spouted bed as the proper gas-solids contact.
Experimental System
The two-dimensional spouted bed is constructed of Plexi glass to allow the observation
of particle movement. Bed dimensions followed the relations to maintain spouted bed
10. stability and adequate solids circulation. The depth of the air inlet orifice must be equal
to the depth of the bed and the width of the air inlet orifice must be within 1/6 and 1/20
of that of the bed. Figure No-6, show the two-dimensional spouted bed used in this
work.
Meisen and Mathur (1978) verified the possibility of using the spouted bed for coating
urea with sulphur. A batch-operated pilot plant was developed and the particles were
coated in a cone-cylindrical spouted bed. The authors concluded that product quality is
a function of air temperature and that the product obtained was comparable to that of
the TVA process for some fixed process conditions.
Weiss and Meisen (1983) modified the basic equipment used by Meisen and Mathur
(1978) and related product quality to the operational conditions. The best quality
product was obtained when the bed was maintained at 80º C. Evaluating the dissolution
rate, D25%, they concluded that quality increased at higher sulphur mass flow rates and
at lower atomizing air flow rates.

developed and constructed is shown in Figure No.-8

With the objective of studying the effects of the temperature of the spouted air, Tas, the
sulphur mass flow rate, Ws, and the atomizing air flow rate, Wat, on the coating process,
a two-level experimental factorial design is used. The results permit the evaluation of
the statistical significance of the influence of the operational variables, specified above,
on product quality in terms of D25%,.
Several preliminary experiments were conducted to establish the methodology and the
ranges for the variables. Table no.-2 presents the operational conditions and the process
times set for the experiments.
Operational Conditions
Tas (0C) 69 82.3
Ws(g/min) 26.7 33.8
Wat(m3/hr) 1.1 1.5
The mass of urea in the bed is fixed at 1300.0 g for all experiments and the process time
is fixed in 20 minutes. The spout air flow rate set at 85% above the minimum spout flow
12. rate, as the mass of sulphur added to the bed causes a mass increase in the bed of about
50%.
Fig. No.-9
Methodology for Determination of Product Quality, D25%
The samples collected during the process of coating and after the end of the
experiments is analysed to determine the sulphur content and the dissolution rate. The
standard TVA test is used to obtain the dissolution rate after seven days: 10g of coated
particles are put in a test tube containing 50ml of water and maintained at 38º C for
seven days. After this period, the tube is shaken slightly and a sample of the solution is
removed. The urea content is obtained by refractometry. The seven-day dissolution rate
is thus given by
D =100 X Mass of the urea dissolved in 7 days/Total mass of the urea in sample
The dissolution rate is a function of the sulphur content of the coated material. Thus, to
compare the quality of the products obtained for different operational conditions, the
dissolution is evaluated for fixed sulphur content. The sulphur content usually specified
is 25%. The value of D25% is found fitting the curve of D versus sulphur content and by
interpolation. The TVA dissolution test described and applied here is a measurement of
the average dissolution of the sample and is not adequate to determine the dissolution
of individual particles.
Why consider slow-release N
1. Consider slow-release N when attempting to reduce environmental losses .
13. 2. Slow-release fertilizer is becoming more cost effective
3. Consider your soil system and cropping system and evaluate which N losses may
be occurring and hindering efficiency.
Fig. No.10
The value of increasing efficiency
Efficiency = more N applied taken up by the crops
1. Increase in yield with same fertilizer rate
2. Maintain yield with reduction in rate.
3. Increase in yield with decrease in rate.
4. Large increase in yield with increase in rate (in each case more N is taken up
per unit applied!)
Disadvantages
Not all sulphur coated urea are created equal. That is sulphur coated urea is only as
good as the weakest point on the coating. If this coating is cracked during transportation
and blending, the content is released as water soluble urea. Some independent studies
have shown that as much as 50% of the nitrogen from sulphur coated urea could be
released within 7days of application.
14. CONCLUSION
Not only do SCU enhance the efficiency of nutrient utilization, they also reduce the
impact on the environment and the possible contamination of the subsurface water
with N. Significantly, less N to leach from controlled-release products than from soluble
N sources. In the future, as a result of SCU for various crops, the demand for controlled-
release products should increase. Numerous studies have been conducted on to
evaluate the quantity of N lost through leaching. Almost without exception, application
of sulphur Coated Urea to turf results in less total N being leached. A primary advantage
to using SCU is the reduced threat of groundwater contamination with N.
Polymer/sulphur-coated fertilizers (PSCF) are hybrid products that utilize a primary
coating of sulphur and a secondary polymer coat. These fertilizers were developed to
deliver controlled-release performance approaching that of polymer-coated fertilizers
but at a much-reduced cost. Although organic nitrogen fertilizers continue to receive a
great deal of attention, it is important to note that sports turf managers have
alternatives to organics. Many of these alternatives areas "environmentally friendly' as
SCU and their release patterns are very often, more predictable.
