PROCESS FOR MONOMER RECOVERY FROM A POLYMERIZATION PROCESS

摘要

The present relates to a process for optimizing the recovery of unreacted monomers from a polymerization process, wherein said process comprises the steps of-recovering a fluid stream generated by the separation of the polyolefin product from the polymerization fluid comprising unreacted monomers and optionally comonomers;-contacting said fluid stream in an absorption zone with a scrub liquid comprising at least one Chydrocarbons, thereby absorbing at least a portion of the unreacted monomers in said scrub liquid; and-withdrawing from said absorption zone a vapor overhead comprising light gas and an absorber bottoms scrub liquid comprising said Chydrocarbons and said unreacted monomer; thereby recovering said unreacted monomer in said absorber bottoms scrub liquid comprising said Chydrocarbons. The present invention also concerns a process for the recovery of unreacted monomers from a gas phase or slurry polymerization process.
