Method for producing fatty acid methyl esters or fatty acid ethyl esters

353 325353 Method for producing CH(OH)and at least one of fatty acid methyl ester (FAME) and fatty acid ethyl ester (FAEE) includes mixing vegetable oils and animal fats, at least one of CHOH and CHOH and at least one first catalyst to transesterify a portion of triglycerides and provide a first mixture. The first mixture is separated, with a first light phase being withdrawn and fed into a second mixer where it is mixed with at least one second catalyst to transesterify a further portion of the triglycerides to provide a second mixture. The second mixture is separated, with a second light phase being withdrawn and mixed with soapless CH(OH)to provide a dispersion which is separated by density difference. A phase containing at least one of raw FAME and raw FAEE is mixed with an aqueous acid, washed with water, with the water being expelled to provide FAME and FAEE product.
