METHOD OF SEPARATING DIMETHYL ETHER FROM AN OLEFIN STREAM
摘要
This invention is directed to a method of removing dimethyl ether from an olefin stream. Dimethyl ether is removed from the olefin stream by first separating the olefin stream into a first stream comprising dimethyl ether and lighter boiling point compounds, and a second stream comprising C4+ olefin and higher boiling point hydrocarbons. The dimethyl ether is then separated from the first stream using extractive distillation.
