Abstract
Provided are industrial processes for producing a fatty acid alkyl ester from a natural oil feedstock or a mixed lipid feedstock, wherein the natural oil feedstock comprises a free (un-esterified) organic acid such as a free fatty acid, comprising: producing fatty acid alkyl esters using an alcoholysis reaction such as a vapor phase alcoholysis reaction or a supercritical alcoholysis reaction, wherein the alcoholysis reaction takes place under conditions comprising: mixing the natural oil feedstock and/or mixed lipid feedstock and alcohol into an alcoholysis reactor or equivalent, and then depressurizing, and then recovering the fatty acid alkyl esters from the alcoholysis reactor or equivalent by distillation in a distillation column, leaving a still pitch or distillation bottoms in the distillation column or equivalent, wherein the fatty acid alkyl esters can be removed from the alcoholysis reactor or equivalent with or without cooling of the reaction mixture prior to depressurization.
