INTEGRATED PROCESS FOR INCREASING BUTADIENE PRODUCTION

摘要

A process is present for increasing the yields of 1,3 butadiene. The process includes recovering 1,3 butadiene from a cracking unit that generates a crude C4 stream. The 1,3 butadiene is separated and the remaining C4 process stream components are further reacted and dehydrogenated to generate 1,3 butadiene in a subsequent process stream. The subsequent process stream is recycled to recover the additional 1,3 butadiene.
