Abstract (en)
[origin: WO2009065452A1] The invention relates to a method for producing fatty acid methyl esters (FAME) or ethyl esters (FAEE) and C3H5(OH)3 from vegetable oils or animal fats in which the triglycerides contained in said oils or fats are transesterified in a base catalytic fashion with CH3OH and/or C2H5OH in the mixers of a plurality of connected mixer-settler stages and the mixtures thus produced are separated in the settlers disposed downstream of the respective mixers into a fatty acid ester (FAE) and a phase containing C3H5(OH)3. The phase containing FAE removed from the settler of the first mixer-settler stage is sent to the mixer of the subsequent mixer-settler stage, where aqueous acid is added thereto and said phase is washed with water in a counterflow. The water contained in the raw FAE thus obtained is removed and the prepared FAE is sent to further processing. The phase containing C3H5(OH)3 obtained from the settler of the second mixer-settler stage is returned to the mixer of the first mixer-settler stage and the phase containing C3H5(OH)3 removed from the settler of the first mixer-settler stage is combined with the phase containing aqueous CH3OH and/or C2H5OH, C3H5(OH)3 and salts obtained upon washing the FAE and the mixture is thermally separated into a phase containing CH3OH and/or C2H5OH, C3H5(OH)3 and an aqueous phase containing C3H5(OH)3 and salts. In order to reduce the concentration of dissolved soaps in the dissolved C3H5(OH)3, a soap-free C2H5(OH)3 is dispersed into the FAE removed from the settler of the last mixer-settler stage and the dispersion is separated into a phase comprising raw FAE and a phase loaded with C3H5(OH)5CH3OH and/or C2H5OH, dissolved soaps, and catalysts.
