Production of Bio-diesel from Jatropha
- 1. Significant reductions in CO2 emissions Reductions in the tail- pipe emissions of Sulphur oxides, particulate s and carbon monoxide • Pakistan consumes around 8 million tons of diesel per annum • Imports 3.4 million tons • Vegetable oils as raw material can lead to thickening in cold climate, fuel flow problems, poor atomization and low efficiency • Higher engine power than conventional diesel fuel • Lower carbon dioxide, carbon monoxide, hydrocarbons and smoke emissions • Similar properties as that of diesel but green fuel PROCESS FLOW DIAGRAM • Less expensive method yet useful and environmental friendly • Free fatty acid contents reduced to 1% • Insulation of storage tanks and pipe-lines would need to be done at low temp zone. • Polluted water needs to be treated first and then used • Storage tanks made of aluminum, steel etc. Are recommended for usage. World’s fossil fuel energy sources crisis to explore renewable energy sources which are more energy efficient & environmental friendly. Jatropha is a bush that grows in regions around the equator as raw material to convert it into biodiesel by Base Catalyzed Trans-esterification reaction. PRODUCTION OF BIODIESEL FROM JATROPHA OIL Alternative to petro-diesel Use abundantly available and of less worth raw material to highly useful fuel oil Preheating and dehydratio n of oil Mixing of catalyst and methanol Esterificatio n of free fatty acids Transesteri fication of triglyceride s Phase separation (decanting) Neutralizing Separation of biodiesel, glycerol and methanol Biodiesel can be used to regulate oil crop prices Neat biodiesel is as biodegradable as sugar and less toxic than salt Biodiesel is also a job creator ABSTRACT OBJECTIVES FEASIBILITY • Substitution fuel for petroleum- derived diesel and can be used in existing diesel engine without modification • Glycol formed reduce the final manufacturi ng costs of the process up to 6.5 per cent. • Jatropha oil produced on commercial basis is less costly LITERATURE SURVEY PROCESS DESCRIPTION ENVIRONMENTAL IMPACTS APPLICATIONS CONCLUSION RECOMMENDATIONS DEMAND 47% 7% 27% 12% 1% 6% Domestic Commercial Industrial Agricultural Streetlights Bulk Supplies Pakistan Energy Consumption 2010 - 2011 R1 R2 H1 H2 S1 C1 C3 C2 Oil with free Fatty Acid Methanol Methanol WaterH2SO4 Water Salts Glycerol Water Methanol, Glycerol Salts Glycerol Salt For Purification NaOH Biodiesel H2SO4 PROJECT ADVISOR : SIR HASEEBULLAH KHAN JATOI Project of ASHRAE Technical Forum, “Fuels and Petrochemicals”
