Abstract:
1. A method for the manufacture of methyl ester and for the separation of the methyl ester from glycerin at an enhanced rate and reduced number of process steps, said process comprising: providing a feed source containing triglyceride, said feed source being substantially water free; blending an alcohol and a catalyst with the feed source to produce a reactant mixture comprising of alcohol, pretreated feed source and catalyst, said reactant mixture being substantially water free; blending a polymer with the reactant mixture, said polymer being selected from the group consisting of; Polydimethylamine-Epichlorohydrin having a cationic charge density of between about 40% and about 60% and a molecular weight of between about 10,000 and about 1,000,000; Poly-Diallyldimethyl-Ammonium Chloride having a cationic charge density of between about 40% and about 60% and having a molecular weight between about 10,000 and about 1,000,000; Acrylamide/Ethanaminium,N,N,N-trimethyl-2-((1-oxo-2-propenyl)oxy)-chloride copolymer having a cationic charge density of between about 4% to about 12% and a molecular weight between about 4,000,000 and about 10,000,000; Polydicyandiamide having a cationic charge density of between about 40% and about 60% and having a molecular weight of between about 3,000 and about 150,000; and Sodium Acrylate Acrylamide copolymer having an anionic charge density of between about 25% and about 75% and a molecular weight between about 8,000,000 and about 28,000,000, and combinations thereof; heating the reactant mixture to a predetermined reaction temperature; reacting the reactant mixture in a substantially non-polar and water free environment for a predetermined reaction time to produce a product mixture comprising of methyl ester, glycerin, alcohol and catalyst; heating the product mixture to a predetermined separation temperature; precipitating a glycerin fraction from a methyl ester fraction; separating the glycerin fraction from the methyl ester fraction; recovering the methyl ester fraction; and recovering the glycerin fraction.
