PROCESSES FOR REDUCING DIENES IN A HIGH PURITY POLYENE STREAM |
摘要 |
Processes for producing a propylene stream having at least 95% propylene and a reduced level of dienes. A selective hydrogenation zone converts dienes into olefins in a stream having at least C3 and C4 olefins from a feed stream including butene and C4 dienes. The selective hydrogenation zone may be disposed between a demethanizer and a deethanzier or it may be disposed downstream of both the demethanizer and the deethanizer. A C3 splitter and an acetylene conversion zone may be utilized. |
