Increasing Yield in the Manufacturing of MPDSAijsrd.com
Meta phenylenediamine 4 sulphonic acid (MPDSA) is one of the important products in the dyestuff sector. The present conventional manufacturing process for MPDSA being carried out at the industry is less efficient and gives an overall yield of about 60 %. But the use of alternative raw materials for the manufacture of MPDSA can give yield as high as upto 80%. In addition, this process also eliminates the use of metal catalysts which cause downstream problems. This method involves the use Metaphenylene Diamine as the raw material instead of 2, 4, dinitrochlorobenzene for the manufacture of MPDSA. A lab scale experiment has been carried out and the overall yield has been found to be higher than that obtained from the conventional process. This paper describes this new manufacturing process and its possible economic benefits. Overall yield is calculated and compared with the conventional process.

Palm Oil As An Alternative Dielectric Transformer CoolantIJRES Journal
Palm Oil is in abundant supply in Benue State in particular and Nigeria in general. But it is ironical to note that this commodity has only found limited use in the kitchen and cosmetic industries This paper deals with the use of Palm oil as an alternative dielectric coolant for distribution level transformers. The research is consequent upon the obvious importance of transformers in electrical power supply networks and the present realization that the existing method of cooling falls short of specifications. Most importantly, is the inability of mineral and petroleum oils to comply with environmental regulation Laws. In order to verify the suitability of Refined bleached and deodorized Palm oil as an alternative dielectric transformer coolant, a detailed investigations of dielectric properties - like dielectric dissipation factor tan δ , relative permittivity δr,, humidity content and breakdown strength under AC stress were carried out. Relevant parameters, with respect to electrical and dielectric properties, are water content and oil temperature as well as field strength and frequency. Results obtained are compared to conventional mineral oil based insulating fluid Shell Diala D. The comparison shows that properties of refined bleached and deodorized Palm oil are better than mineral oil Shell Diala D particularly the breakdown voltage and the humidity content, the dielectric dissipation factor and relative permittivity also satisfy operation requirements. Based on results obtained from this work, it is recommended that a practical refined bleached and deodorized Palm oil based dielectric coolant can be incorporated into transformer insulation systems in the electricity distribution networks with little or no modifications.

Exploration of the Potential of Reclaimed Waste Cooking Oil for Oil-Immersed ...TELKOMNIKA JOURNAL
In this study, reclaimed waste cooking oil is proposed as an alternative insulating liquid for oil-immersed power transformers. Reclamation is carried out by heating a mixture of waste cooking oil and Fuller’s Earth adsorbent and followed by filtration. Propyl gallate antioxidant is then added into the filtered oil. Four oil samples are investigated in this study: (1) new cooking oil (NCO), (2) waste cooking oil (WCO), (3) reclaimed oil (RWCO) and (4) reclaimed oil with propyl gallate antioxidant (RWCOPG). The AC breakdown voltage, moisture content and total acid number is measured for all oil samples according to the ASTM D1816, ASTM D1533 and ASTM D974 standard test method, respectively. The results show that the AC breakdown voltage is highest for the RWCOPG sample (28.08 kV), which is 0.4% higher than the standard requirement of 20 kV. The moisture content for this sample is 180.60 ppm, which is still below the allowable limit of 200 ppm. However, the total acid number is highest for the RWCOPG sample which suggests that it has high acidity. It is indicated that the antioxidant-reclaimed waste cooking oil has potential to be used as an insulating liquid for oil-immersed power transformers, but much work is still needed to reduce the total acid number of this oil.
Effects of Extraction Methods and Transesterification Temperature on the Qual...IJRTEMJOURNAL
Jatropha curcas oil has been considered a promising alternative fuel for compressing ignition
engines. However, its qualities and utilizations have been affected by so many factors such as extraction
methods, temperatures, reactants, etc. As a result, this work was aimed at studying the effects of extraction
methods and transesterification temperature on the qualities of biodiesel from jatropha oil seeds. Three methods
of extraction (milling hydraulic, and defatting; milling, toasting, and defatting: and sand roasting, dehulling,
milling and defatting) were employed to produce the three different samples A, B, and C respectively. The yields
of the oils obtained were measured. Oil qualities of the oil like: specific gravity, viscosity, free fatty acid,
saponification value, peroxide value, pH and iodine value content of the oil were determined. The extracted oils
were subjected to transesterification process at a various temperature by treatment with ethanol using
potassium hydroxide as catalyst. Average yield of biodiesel was 70.62 %, 74.33% and 79.41% of raw oil from
sample A, B and C respectively. The specific gravity, viscosity, free fatty acid, saponification value, peroxide
value, pH and iodine value content of the oil of sample were A (0.904, 3.240mm2/s, 0.431% ,64.80mg/kg,
2.00mg/kg, 7.38 and 140.61, respectively); sample B (0.903, 3.130mm2/s, 0.423%, 58.91mg/kg, 11.00mg/kg,
7.02 and 55.33, respectively); sample C (0.908, 3.324mm2/s, 0.368%, 52.73mg/kg, 2.00mg/kg, 8.50 and 143.65
respectively). The result revealed that different extraction methods and transesterification temperature have
actually affected the quantity and quality of biodiesel produced from Jatropha oil seeds. Processing of the oil
seeds by roasting dehulling, milling and defatting and transesterification at 700C gave the highest oil yield and
the most acceptable chemical properties.
Estimating the Amount of Moisture Content in Crude Oil SamplesIRJESJOURNAL
Abstract :- Determination of the amount of water in crude oil and petroleum products has always been important. Rather than paying crude oil prices for water, contracts have been based on "net dry oil". This is calculated by reducing the total gross standard volume (GSV) by the amount of water and sediment present as determined by analysing a sample of the oil. Accurate analysis for the water content is usually more difficult than the determination of gross volume, temperature, and gravity of the oil.

Characterization of biodiesel produced by meth butanolysis of castor oileSAT Journals
Abstract Crude Castor oil was transesterified using methanol, mixtures of methanol and butanol in molar percentages and potassium hydroxide as catalyst. The optimum reaction conditions, based on the percentage yield of biodiesel, were 45 mins reaction time at 650C and 1.5w/w% catalyst. The alcohol/oil ratio and agitation rate were both held constant at 12:1 and 450rpm respectively throughout the process. The yield of biodiesel from castor oil at such optimum reaction conditions were 87.1%, 85.7 % and 81.7 for 100%, 95% and 90% methanol-butanol molar blends respectively. . The specific gravities at 150C were 0.898 and 0.902ml/g, kinematic viscosities at 400C varied from 6.4 to 7.8 cSt. The calorific values were between 10690 and 10708 cal/g and the flash points were found to be within the range 144 to 1500C. The standard specifications for biodiesel (ASTM D67651) show that the specific gravity, flash point and calorific value requirements were satisfied. The higher viscosity (above 6.0 cSt.) can be controlled by the use of additives. Alternatively, blending with petroleum diesel will lead to improvement of the flow properties of the biodiesel fuel. Keywords: Transesterification, Castor oil, methanol/butanol molar blend, Biodiesel yield.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

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!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
