Abstract
A process and apparatus integrate recovery of propylene from a pyrolysis reactor and a paraffin dehydrogenation reactor. A stripping column for fractionating a dehydrogenation stream is coupled with a demethanizer column for fractionating a pyrolyzed stream. The stripping overhead stream comprising C2− hydrocarbons are fractionated with the pyrolyzed stream in the demethanizer column. The coupling omits the need for a conventional deethanizer column and separate refrigeration system in the propane dehydrogenation unit.
