Extraction kinetics of fatty acids ethyl esters (FAEE) from oil phase using aqueous ethanol

There is a need for alternative energy sources to replace petroleum based fuels due to the world’s crude oil reserves, global warming and environmental concerns. Biodiesel is clean, biodegradable, non-toxic and renewable fuel which is considered to be the best substitution for diesel fuel. In additi...

description There is a need for alternative energy sources to replace petroleum based fuels due to the world’s crude oil reserves, global warming and environmental concerns. Biodiesel is clean, biodegradable, non-toxic and renewable fuel which is considered to be the best substitution for diesel fuel.
