Abstract: A process for withdrawing polyolefins from a reactor includes: continuously withdrawing a liquid solution stream from a solution polymerization reactor and passing the liquid solution stream into a low pressure separator; withdrawing a first vapour stream and a first liquid stream from the separator and passing the first vapour stream into a washing column; withdrawing a second vapour stream from the washing column and feeding it via a condenser line to a condenser; cooling the second vapour stream in the condenser so that part of the second vapour stream condenses, producing a condensed second vapour stream and an uncondensed second vapour stream; passing the condensed second vapour stream to an upper part of the washing column via a reflux line; withdrawing a second liquid stream from the washing column and passing at least part of the second liquid stream to the separator via a recycling line; and recovering heat.
