Abstract:- Biodiesel is a mixture of mono-alkyl esters of long chain fatty acids derived from a renewable lipid feedstock. It can be used as an alternative fuel as the fossil fuels are getting depleted day by day. Moreover the use of biodiesel leads to the substantial reduction in the pollution caused by PM, HC, CO etc. This paper consists of the production of biodiesel from waste cooking oil using alkaline catalysts NAOH and KOH and cosolvent acetone in the presence of methanol. Waste cooking oil is used because of its high oil content and abundant availability. This method used is co-solvent method.
Biodiesel production from neem oil –an alternate approachIJERA Editor
In this study, neem oil which is one of the abundant non-edible oils in India, Nepal, Pakistan, Sri Lanka and bangladesh is used for biodiesel production. The conventional 2-step transesterification production of biodiesel using sulphuric acid and potassium hydroxide as catalysts is carried out. The optimum process parameters like reaction time, temperature, catalyst loading and methanol-oil molar ratio were investigated with respect to maximum yield. A maximum yield of 88% biodiesel is obtained via this method. A novel technique to produce biodiesel via complete hydrolysis followed by acid esterification is developed. Optimum reaction conditions were found to be 100ml 0.5N sulphuric acid loading, reaction temperature of 40ºC and reaction time of 2 hours. This resulted in a maximum FFA of 82%. Then acid esterification was carried out at the following reaction conditions of 0.55:1 v/v methanol-oil-ratio, 0.5% v/v H2SO4 acid catalyst loading, 50˚C and 4 hours reaction time. A maximum biodiesel yield of 92% was obtained by this method. The viscosity of biodiesel produced by this method as well as the other physicochemical properties, were found to be in compliance with international standard.
Biodiesel is an elective fuel like regular or 'fossil' diesel. Biodiesel can be delivered from straight vegetable oil, creature oil/fats, fat and waste cooking oil. The procedure used to change over these oils to Biodiesel is called transesterification. This procedure is depicted in more detail beneath. The biggest conceivable wellspring of appropriate oil originates from oil yields, for example, rapeseed, palm or soybean. In the UK rapeseed speaks to the best potential for biodiesel creation. Most biodiesel created at present is delivered from squander vegetable oil sourced from eateries, chip shops, modern nourishment makers, for example, Birdseye and so forth. Despite the fact that oil directly from the horticultural business speaks to the best potential source it isn't being delivered economically essentially in light of the fact that the crude oil is excessively costly. After the expense of changing over it to biodiesel has been included it is basically too costly to even think about competing with fossil diesel. Squander vegetable oil can regularly be sourced for nothing or sourced effectively treated at a little cost.

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.

In this work, statistical modeling and optimization of biodiesel production from Azadirachta Indica(neem) using co-solvent technique via a two-step transesterification process was carried out. Neem oil was extracted from neem seeds and properties such as moisture content, specific gravity, acid value, saponification value and iodine value were determined. The experimental design used was Central Composite Design. The range of factor levels used for the Central Composite Design were reaction temperature (30°C to 46°C), catalyst amount (0.8% to 1.2%, w/w), reaction time (20 to 40min) and methanol-to-oil molar ratio (5:1 to 9:1). The co-solvents used were methanol and diethyl ether. The co-solvent-to-methanol volume ratio for all the experimental runs was kept constant at 1:1. Also the biodiesel produced was characterized for some important properties including acid value, specific gravity, saponification value, iodine value, cetane number, ester value, kinematic viscosity, flash point, pour point and cloud point. Optimized biodiesel yield of 84.77% was obtained for reaction time of 35 min, catalyst amount of 1.10g, reaction temperature of 34°C, and oil-to-methanol molar ratio of 6:1. The cetane number (51.733), specific gravity (0.8881g/cm3), flash point (134oC) and kinematic viscosity (5.86mm2/s) of the produced biodiesel met the ASTM specifications. The results of characterization of the biodiesel revealed that biodiesel can be produced at lower reaction conditions and with comparable fuel property with biodiesel produced using conventional methods.

Biodiesel Production from waste Oil with Micro-Scale Biodiesel System Under L...IJERDJOURNAL
ABSTRACT:- The aim of this project is to produce biodiesel from waste oil. The use of vegetable oils as diesel fuel started with the invention of diesel engines in the 1900s and is also common in many countries today. The fact that the oils used in biodiesel production are also an important input of the food industry is a limiting factor in production. For this reason, it is aimed to produce biodiesel from waste oil which can not be assessed in food production in this study. The most important contribution of the study to biodiesel researches is the establishment of a small-capacity biodiesel unit in laboratory conditions. The waste oils from the food production facilities of Namık Kemal University (NKU) have been collected and biodiesel has been produced using two different experimental methods. The analyses that determine the quality of the biodiesel samples have been carried out by Energy Agriculture Research Center of Black Sea Agricultural Research Institute in Republic of Turkey Ministry of Food, Agriculture and Livestock. As a result of the research, it has been determined that the biodiesel fuel obtained by the B-1 method using KOH as a catalyst conforms to the standards and can be used with confidence in diesel engines.

Abstract Gradual depletion of world petroleum reserves and increase in the exhaust emissions day by day have led to an urgent need for alternative fuels to replace diesel. Vegetable oils biodiesel is considered as an alternative for diesel because of their properties which have been close to pure diesel. In the present study non edible vegetable oils like Honge and Jatropha oils biodiesel and their blends were used as fuel in a constant speed direct injection diesel engine. Further effect of injection pressure on the performance parameters such as brake thermal efficiency, brake specific fuel consumption, brake power and emission parameters such as HC, CO and NOX were investigated in a constant speed direct injection diesel engine with varied injection pressures of 180, 200 and 220 bar.The test results showed that Honge and Jatropa oil biofuel blends are having good performance and emission results at 200 bar injection pressure when compared to 180 and 200 bar injection pressure. The test results also showed that performance and emission results of Honge and Jatropa biofuel blends are near to that of the results obtained for pure diesel and they can be used to replace pure diesel.

Production of Biodiesel using waste temple oil from Shani Shingnapur temple (...IJEAB
In India, due to various mythological and religious reasons hundreds of devotees pour oil over the idols in Hanuman or Maruti and Shani temples. The oil once poured cannot be reutilized and was ultimately wasted. These waste temple oil from Shani Shingnapurwas used to produce biodiesel. Immobilized Pseudomonas aeruginosa was used to catalyze transesterification of waste temple oil. The cells of P.aeruginosa were immobilized within the sodium alginate. Biodiesel production and its applications were gaining popularity in recent years due to decreased petroleum based reserves. Biodiesel cost formed from waste temple oil was higher than that of fossil fuel, because of high raw material cost.To decrease the cost of biofuel, waste temple oil was used as alternative as feedstock. It has lower emission of pollutants; it is biodegradable and enhances engine lubricity. Waste temple oil contains triglycerides that were used for biodiesel production by chemical and biological method.Transesterification reaction of oil produces methyl esters that are substitutes for fatty acid alkyl biodiesel fuel. Characteristics of oil were studied such as specific gravity, viscosity, acid number, saponification number.Parameters such as temperature,oil: methanol ratio were studied and 88%, 96% of biodiesel yield was obtained with effect of temperature and oil: methanol ratio on transesterification reaction. Withaddition ofNaOH or KOH to fatty acids which formed salt known as soap,which is excellent emulsifying and cleaning agents.

Production and Application of Bio-diesel in Compression Ignition Engineijsrd.com
The continuous increasing demand for energy and diminishing tendency of petroleum resources has led to the search for alternative renewable and sustainable fuel. Biodiesel seems to be a solution for future and being viewed as a substitute of Diesel. The vegetable oil, fats, grease are source of feedstock for the production of biodiesel. Out of four methods viz. dilution, micro emulsion, thermal cracking and Transesterification, the last one is used to produce biodiesel and reduce viscosity. Biodiesel is more suitable for use as an engine fuel rather than straight vegetable oils for a number of reasons; the more notably is its low viscosity. The aim of the paper at hand is towards the production of biodiesel from vegetable oils viz. Karanja, Jatropha by Transesterification process. Fuels were manufactured by direct blending 5% of biodiesels, namely, Karanja and Jatropha and Rice Bran vegetable oil using Magnetic stirrer. The physical properties of the fuels were also found out. Later, these fuels were run in Compression Ignition engines to test and compare the performance and pollution characteristics of fuels.
Due to increase demand of energy, increasing price
of petroleum fuels, depletion of petroleum fuels, and
environmental pollution by these fuel emissions, it is very
necessary to find the alternative fuels. This work focused on use
of hybrid blends of Karanja and Cottonseed oil Biodiesels. In this
work 20% and 25% blends are used and the performance and
emission tests were conducted on single cylinder, 4-stroke, water
cooled CI engine by running the engine at a speed of 1500rpm, at
a compression ratio of 16.5:1 and at an injection pressure of
205bar and performance parameters like BP, BSFC, BTE and
the emissions like CO, HC and NOx are compared. It was found
that the blends gave comparatively good results in respect of
performance and emissions.

Flexible Design Processes to Reduce the Early Obsolescence of BuildingsIRJESJOURNAL
Abstract:- This work intends to analyze the processes of flexibility to improve the adaptability to the users and to define some strategies to delay building obsolescence. Some approaches that address the architectural flexibility processes are studied to understand the rapid transformation of user lifestyles and changes in needs and performance building requirements. Obsolescence is often characterized by the lack of flexibility in the structure and walls, as well as services that change rapidly according to the different uses of buildings. This poses a threat to the built environment, since a large number of buildings are demolished having still years of useful life. In this way, different types of obsolescence are analyzed, focusing on some structural, economic, functional and social aspects of the construction and the use of buildings, seeking the capacity to design and produce adaptive buildings that are more resilient to obsolescence. Thus, some concepts of flexibility and flexible process are presented to promote adaptability in buildings. However, flexibility is a complex process, a long way to achieve adaptability to the built environment and the changing needs of users. The method used in this analysis takes into account the diversity of the design process, making some considerations about the interrelation of the social, functional and technical aspects. Finally, some conclusions about the design methods faced by a flexible approach process can lead to more useful and adaptable spaces for future transformations in order to extend the life cycle and prevent early obsolescence of buildings.

Flight Safety Case Study: Adi Sucipto Airport Jogjakarta - IndonesiaIRJESJOURNAL
Abstract: Adi Sucipto Airport-Jogyakarta is an airport with enclave civil status or as TNI-AU airbase (civilian airport within the military area) has limited infrastructure with Azimuth Runway 09-27, has no RESA (Runway End Safety Area). The calculation results using Acceptable Safety Level (ASL) standard 1 x 10-7 shows that the probability of accident risk at wet runway condition is greater than in dry condition. Runway Excursion occurs at the airport, especially when the runway is wet and overrun due to hydroplaning and the plane deviates from the center of runway as well as the aircraft wheels are in contact with ground or obstacle surface outside the runway. It means the thicker layer of water above the runway will cause increased risk of accidents on the runway. This is why standing water should be immediately removed from the runway as quickly as possible. Mitigation efforts need to be done simultaneously with recovery by adding RESA and other preventive efforts in order to water patch and standing water does not exceed 2 mm and apply the mandatory of SOP consistently at the airport.

Annealing Response of Aluminum Alloy AA6014 Processed By Severe Plastic Defor...IRJESJOURNAL
Abstract: In this paper the study of micro structural stability during annealing with respect to time of conventionally grains (CG) and ultrafine-grained (UFG) of Aluminum AA6014 i s carried out. It has been observed that, the effect of the second phase magnesium-silicon particles in the CG and UFG AA6014 samples leads to a rapid hardness which increases from 40HV10 to 70HV10 within 7 days. Artificial aging shows that the material hardness even increased after 20 hours of annealing at 180°C. In total 30 hours of annealing, the hardness arrives at its maximum and then reduces due to the formation of Mg2Si precipitates, which rise in size and change their coherency. The precipitates cannot efficiently pin the dislocations and act as barriers to the dislocation motion which indicate an overall decrease in the hardness. It also has been found that the ultrafinegrained AA6014 alloy loses its thermal stability at approximately 200°C and recrystallized at 300°C. Thermal stability is strongly dependent on the material purity, second phase particles and/or oxide particles which may break up during rolling and lead to some dispersion strengthening.

Abstract: - A noncontact method for respiration rate monitoring using thermal imaging was developed and evaluated. Algorithms to capture images, detect the location of the face, locate the corners of the eyes from the detected face and thereafter locate the tip of the nose in each image were developed. The amount of emitted infrared radiation was then determined from the detected tip of the nose. Signal processing techniques were then utilised to obtain the respiration rate in real-time. The method was evaluated on 6 enrolled subjects after obtaining all ethical approvals. The evaluations were conducted against two existing contact based methods; thoracic and abdominal bands. Results showed a correlation coefficient of 0.9974 to 0.9999 depending on the location of the ROI relative to the detected tip of the nose.

Abstract :- Filtration is used in many industries to separate water from the solid. It is important to find fluid loss in drilling, cementing, fracturing, and almost every other type of downhole treatment design. The filter cake characterization is very essential for well selection of drilling fluid problems and formation damage. Therefore this study is taken up to experimentally investigate the effect of different concentrations of CMC, Starch, Wood fibers, Soda ash, Caustic soda, Bentonite and Barite on filtration loss and formation damages. Three different samples are used in this study at different concentration and a comparison is made. Although the discussion presented here is confined to fluid loss during drilling. Water-based drilling mud’s including Bentonite is wellknown and is being widely used in the petroleum industry. Among the important functions of water-based drilling fluid were to form filter cake on the wall of the well bore, prevent water leakage, and maintain the stability of the well wall. The properties of the water-based drilling fluid, such as the rheology and filtration loss, are affected by the fluid loss additive. Polymers, which are nontoxic, degradable, and environment friendly, are the best choice to be used as drilling fluids additives.

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!

Abstract:- Biodiesel is a mixture of mono-alkyl esters of long chain fatty acids derived from a renewable lipid
feedstock. It can be used as an alternative fuel as the fossil fuels are getting depleted day by day. Moreover the
use of biodiesel leads to the substantial reduction in the pollution caused by PM, HC, CO etc. This paper
consists of the production of biodiesel from waste cooking oil using alkaline catalysts NAOH and KOH and co-
solvent acetone in the presence of methanol. Waste cooking oil is used because of its high oil content and
abundant availability. This method used is co-solvent method.
Keywords: acetone, biodiesel, catalyst, optimization, waste cooking oil.

I. INTRODUCTION
Biodiesel is an alternative fuel derived from vegetable oil or animal fat. It is obtained from renewable
raw materials. It has various advantages. The emission profile of biodiesel is satisfactory and it is biodegradable.
It is an ecological fuel and is not dangerous merchandise. The feedstock we use is the waste cooking oil because
of its abundant availability and high oil content. Acetone is used as the co-solvent. It is a colorless, mobile,
flammable liquid. The feedstock is comprised of recycled oil and grease from restaurants and food processing
plants. NAOH and KOH are used as catalysts in the presence of methanol. The method we use to produce
biodiesel is co-solvent method. The relevance of using co -solvent for the production of biodiesel and its effect
in the reaction time, reaction temperature and yield of biodiesel is studied. The produced biodiesel from waste
cooking oil are checked with the ASTM Standards to clarify the quality of biodiesel obtained in the experiment.
II. MATERIALS AND METHODS
The materials used for the production of biodiesel are
1. Waste cooking oil
2. KOH and NAOH
3. Methanol
4. Acetone
The method employed in the production is co-solvent method and the equipment used is magnetic stirrer.

magnetic stirrer under a temperature of 60 ͦ C for 1 hour. Separate the product using separating funnel.
1.12 Test 2:
Take 100 ml of preprocessed oil. Add 16 ml of methanol and 1gm of NAOH and 1 ml of acetone keep
the mixture in magnetic stirrer under a temperature of 55 ͦ C for 30 min. Separate the product using separating
funnel.
1.13 Test 3:
Take 100 ml of preprocessed oil . Add 16 ml of methanol and 1gm of KOH and keep the mixture in
magnetic stirrer under a temperature of 60 ͦ C for 1 hour. Separate the product using separating funnel.
1.14 Test 4:
Take 100 ml of preprocessed oil. Add 16 ml of methanol and 1gm of KOH and 1 ml of acetone keep
the mixture in magnetic stirrer under a temperature of 55 ͦ C for 30 min. separate the product using separating
funnel.
Biodiesel is obtained from all the tests and filter it from glycerol using a separating funnel and wash it
to obtain the pure biodiesel.

Table: Factorial design for optimizing biodiesel.
It is found that by using acetone as the co –solvent we can reduce the reaction time and temperature to
yield almost the same volume percentage of biodiesel obtained from normal case.
The properties of biodiesel obtained is checked with the ASTM Standards
IV. CONCLUSION
The presence of co-solvent makes the system homogeneous. The co-solvent consumed for getting high
yield is very less and the reaction temperature is subsequently reduced. So this method is a relevant method
which can be used for the production of high yield biodiesel. The biodiesel obtained from this method is of good
quality. It can be used in its pure form or can be blended with petroleum for commercial uses. This is very cost –
effective method of producing biodiesel.
