PROCESS FOR MONOMER RECOVERY FROM A POLYMERIZATION PROCESS |
摘要 |
<p>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 C 4-10 hydrocarbons, thereby absorbing at least a portion of the unreacted monomers in said scrub liquid; and
- withdrawing from said absorption zone (i) a vapor overhead comprising light gas and (ii) an absorber bottoms scrub liquid comprising said C 4-10 hydrocarbons and said unreacted monomer; thereby recovering said unreacted monomer in said absorber bottoms scrub liquid comprising said C 4-10 hydrocarbons. The present invention also concerns a process for the recovery of unreacted monomers from a gas phase or slurry polymerization process, and also concerns a process for the production of polyolefins.</p> |
