PRODUCTION OF PRODUCTS FROM FEEDSTOCKS CONTAINING FREE FATTY ACIDS

摘要

The present invention provides a method for producing a refined fatty acid alkyl ester (FAAE) product from feedstocks containing free fatty acids. The method comprises glycerolysis and transesterification processes combined with end-product refining. Products produced from a transesterification reaction are separated into a crude FAAE stream and a crude glycerin stream. The crude glycerin stream is further processed to produce a glyceride stream from which additional FAAEs may be produced.
