Abstract:
The invention removes oxygenate from an olefin rich gas stream, the process comprising: (a) reacting an oxygenate, in a reaction zone in the presence of a molecular sieve catalyst, at a temperature from 350 to 1000° C., to produce an effluent stream, comprising at least oxygenate, olefin, water and acidic by-products; (b) cooling the effluent stream and contacting it with a first aqueous stream in a quench zone to produce an aqueous stream and an olefin rich gas stream; (c) compressing the olefin rich gas stream in one or more compressors in series to produce a compressed gas stream, (d) cooling the compressed gas stream and separating condensed material from said gas stream after each of the one or more compressors.
