Abstract
A process and apparatus integrate recovery of propylene from a pyrolysis reactor and a paraffin dehydrogenation reactor. A common depropanizer fractionates propane feed and pyrolysis reactor effluent to provide a C3 stream. A dividing wall may be used in the column to prevent cross contamination by the pyrolysis effluent with the propane dehydrogenation feed.
