    摘要: A method produces fatty acid esters by transesterification of fats and oils with the aid of an alcohol, at a high pressure and temperature. Unreacted alcohol is separated inline from the reaction mixture and continuously recycled into the transesterification process. The separation is performed by obtaining a vapour phase and higher density phases of the reaction mixture and concentrating the alcohol in the vapour phase.
