| Abstract: | The basic principles of membrane technology for recovering propylene from uncondensable gas vented from recovery units of polypropylene off-Gas were described,and ways to improve propylene recovery analyzed and discussed.The uncondensable gas contained about 40%～50% of propylene.The vapor gas membrane separation system is able to recover over 90% of propylene from the uncondensable gas.Advantages of the membrane system are easy operation,limited space,and obvious economic benefit. |
