Patent ID: 7087685

Claim:
A process for recycling a liquid to a polymerization reactor, the method comprising: vaporizing a portion of a slurry withdrawn from a polymerization reactor to form a first vapor stream, wherein the slurry comprises solid polymer particles in a liquid medium, and the liquid medium comprises a primary component and heavies which are components less volatile than the primary component; separating the first vapor stream from the slurry; condensing a first portion of the first vapor stream in a first condensing zone to form a first liquid, and passing the first liquid to a liquid collection zone; passing a second portion of the first vapor stream to the liquid collection zone without passing the second portion through the first condensing zone; separating contents of the liquid collection zone into a second vapor stream and a second liquid; passing the second liquid to a heavies purification zone; condensing the second vapor stream in a second condensing zone to form a third liquid; and recycling the third liquid to the polymerization reactor without fractionating the third liquid to remove heavies from the third liquid.
