| Abstract: | Propylene recovery at a rate above 85% from the non-condensable gas released from polypropylene plant was carried out with membrane separation technique. Additional 2-4 tons of propylene could be collected per day with the membrane recovery system equipped on the existing plant. The investment for the innovation could be recouped in a very short term. |
