Abstract
A process for cracking an olefinic feed comprising diolefins and monoolefins is provided. The process comprises selectively hydrogenating the olefinic feed in a hydrogenation reactor to convert the diolefins to monoolefins to provide a hydrogenated effluent stream. The hydrogenated effluent stream is vaporized to provide a vaporized hydrogenated effluent stream. The vaporized hydrogenated effluent stream is passed to an olefin cracking reactor to provide a cracked olefin stream comprising Cand Colefins. The cracked olefin stream is passed to a recycle column to provide one of an overhead vapor stream comprising Chydrocarbons or a side draw vapor stream comprising C. At least a portion of the overhead vapor stream or the side draw vapor stream is recycled to the olefin cracking reactor.
