PROCESS FOR THE PRODUCTION OF FATTY ACID ESTERS |
摘要 |
In a process for producing fatty acid esters, a fatty acid or fatty acid mixture is subjected to esterification with a lower alkanol in an esterification reactor maintained under esterification conditions to form a stream comprising the corresponding lower alkyl ester(s). An overhead stream comprising unreacted lower alkanol, water and a heavy organic content of one or more of lower alkyl ester and/or acids is recovered from the reactor. The overhead stream is subjected to distillation in a first distillation column to separate a portion of the lower alkanol from a stream comprising the water, the remaining lower alkanol and the heavy organic content. This stream is recovered and subjected to distillation in a second distillation column to provide an overhead stream comprising lower alkanol and at least a major portion of the heavy organic content and a water stream having a reduced heavy organic and alkanol content. |
