The invention relates to integration of MTO with on purpose butadiene. A process is presented for the production of 1,3-butadiene. The process includes separating C4 olefins from an olefin stream generated by a methanol to olefins conversion reactor. The C4 stream is process and 1,3-butadiene is recovered, The remaining C4 stream is passed to a dehydrogenation unit to generate more butadienes. The dehydrogenation process stream is processed to recover products, such as 1-butene and 1,3-butadiene. |
