摘要

A method for recovering volatile components from reformer effluent condensate and fusel oil in a methanol plant is disclosed. The fusel oil is stripped with steam to produce an overhead vapor stream of steam and stripped organic components which is recycled to the feed to the reformer. Also disclosed are a methanol plant with a fusel oil stripper; and a unitized stripper column for treating fusel oil and process condensate wherein steam containing volatile gases stripped from the process condensate is used to strip the fusel oil. The present invention improves yield and reduces or eliminates liquid fusel oil waste by recycling volatile organic components contained in the fusel oil to the feed of the reformer.
