  • Method for preparing fatty acid esters with alcohol recycling
    Patent number: 8076498
    Abstract: 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.
    Type: Grant
