The present invention provides a method and reactor system for hydrogenating acetylenes present in the olefin stream derived from the following streams, alone or in combination: petroleum catalytic cracking process and/or oxygenate-to-olefin reactor, such as methanol-to-olefin (MTO) reactor, in an olefin production plant before the distillation steps, wherein the acetylene hydrogenation occurs before or just after the acid gas removal step. |
