Abstract: Method and apparatus for esterification of fatty acids or fatty acids contained in fats and oils with lower monovalent alcohol having 1 to 4 carbon atoms, comprising combining in a reaction section the fatty acids or fatty acids contained in fats and oils, and the alcohol to form a mixture, the combining forming enlarged interphases of the mixture by high or powerful dynamic shear forces and turbulence; at least one of strong mineral acid and acid ion exchange resin being present in the reaction section or a post-reaction section; starting esterification in the reaction section under pressure of 2 to 500 bar, and reducing pressure during the esterification so that a high interphase is maintained; and the esterification is carried out in the reaction section at a temperature of 50 to 300° C.

Abstract: Method for producing fatty acid methyl ester, including compounding saturated and unsaturated higher fatty substances from at least one of vegetable and animal with an alkaline solution dissolved in alcohol to form a mixture. The method also includes emulsifying the mixture to reach a chemical balance state in a reaction section, wherein fats are transesterified into fatty acid methyl ester, wherein border surfaces of the mixture are enlarged by dynamic turbulence in the reaction section and the transesterification is performed under pressure, and wherein the pressure is reduced during transesterification. The method further includes after reaching a chemical balance state, separating residues from the fatty acid methyl ester in a phase separation section. Apparatus for producing fatty acid methyl ester.
