  • Patent number: 8193383
    Abstract: In a process for producing fatty acid methyl ester (FAME) from fats or oils by transesterification with methanol in the presence of an alkaline catalyst in at least two reaction stages traversed in succession, each consisting of a stirred-tank reactor and a downstream separator, a phase containing FAME and a phase containing glycerol are generated, which are separated in the separator, wherein the phase containing FAME is recirculated into the stirred-tank reactor of the next succeeding reaction stage and the phase containing glycerol is recirculated into the stirred-tank reactor of the first reaction stage, and the crude FAME withdrawn from the separator of the last reaction stage is transferred into a separator and the FAME withdrawn is dried.
