    • 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.
    • 本发明涉及从聚合方法优化未反应单体的回收方法,其中所述方法包括以下步骤:回收通过将聚烯烃产物从包含未反应单体和任选的共聚单体的聚合流体分离而产生的流体流; 使吸收区中的所述流体流与包含至少一种氢氧化碳的洗涤液接触,从而吸收所述洗涤液中的至少一部分未反应单体; 并从所述吸收区抽出含有轻质气体的蒸汽塔顶和包含所述氢氧化碳和所述未反应单体的吸收塔底洗涤液; 从而在所述吸收塔底洗涤液中回收所述未反应单体。 本发明还涉及从气相或淤浆聚合方法回收未反应单体的方法。

    • The present invention relates to an apparatus for degassing polymer powder comprising a chamber having a first end and a second end opposite to each other, said chamber being equipped with at least one powder inlet and at least one gas outlet at the first end and with at least one powder outlet and at least one gas inlet at the second end, and a valve provided with a powder entry and a powder exit and arranged at the powder outlet of said chamber. The apparatus is characterised in that said chamber is equipped with a gas line joining a gas exit of the valve to the inside of the chamber at a position that is at a distance h2 from the first end (20), said distance h2 being 20-70% of the height H of the chamber and at a distance l1 from a wall of said chamber, said distance being l1 5-50 % of the largest diameter L of the chamber. The invention also relates to a method for degassing polymer comprising flushing the polymer powder in a chamber with a flow of flushing gas, wherein at least a part of flushing gas exiting the chamber through a powder outlet is re-introduced into said chamber. ® KIPO & WIPO 2009
