Abstract
In a process for producing fatty alcohol, fatty acid is subjected to esterification with a lower alkanol to form a stream of lower alkyl fatty acid ester(s). The stream is vaporized and then subjected to hydrogenation. The stream is then subjected to transesterification in a wax ester reactor to convert at least a portion of the lower alkyl fatty acid ester(s) to lower alkanol and wax ester(s). The resulting stream is then separated to yield a fatty alcohol(s) steam, a wax ester(s) stream, and an overhead stream comprising fatty alkanol(s) and alkane. The overhead stream is reacted in a wax ester reactor to convert at least a portion of the lower alkyl fatty acid ester to lower alkanol and wax ester(s). The wax ester(s) formed from the alkane is separated, along with any water and/or lower alkanol present.
