Abstract
Processes are provided to produce a dilute ethylene stream and a dilute propylene stream from a cracked gas stream. One process comprises separating the cracked gas stream to produce a C stream and a C stream; hydrogenating the C stream in a hydrogenation zone to remove a portion of the acetylene to produce the dilute ethylene stream and routing the C stream to storage or other process unit. Another process comprises separating a cracked gas stream in a depropanizer zone to form a C stream and a C stream; separating the C stream in a deethanizer zone to form a C and a C stream; hydrogenating a portion of the acetylene in the C stream in a hydrogenation zone to produce a dilute ethylene stream; and routing the C stream to storage or other process unit.
