Production of products from raw materials containing free fatty acids

The present invention provides a method for producing a refined product of alkyl ester of fatty acids (FAAE) of raw materials containing fatty acids. The method comprises glycerolysis processes and refining combined with transesterification final product. The products produced from a transesterification reaction are separated into a stream of raw FAAE and a stream of glycerin bruto.La crude glycerol stream is further processed to produce a stream of glycerides from which can be produced additional FAAE.
