  • Patent number: 8436109
    Abstract: The present invention relates to a process for producing steam using heat recovered from a polymerization reaction. In particular, the present invention relates to a process for producing steam using heat recovered from a polymerization reaction for producing polyolefin, comprising the steps of: thermally contacting said polymerization reaction with a cooling fluid such that the cooling fluid removes heat from said reaction, thermally contacting at least part of said cooling fluid with at least one absorption cycle thereby transferring heat from the cooling fluid to said absorption cycle, using said absorption cycle to produce steam from a condensate, wherein the cooling fluid is used as a hot source for heating at least one evaporator and at least one generator comprised in said at least one absorption cycle. The present invention also relates to a process for cooling a polymerization reaction using a process as described herein. Said invention also relates to a polyolefin producing unit.

  • Publication number: 20130102741
    Abstract: The present invention relates to a process for improving the devolatilization of polymer slurry produced in an olefin polymerization reactor. The process is characterized in that it involves an adjustment of the temperature of the interior surface of the flash line for periodically transferring polymer slurry from the polymerization reactor to a downstream processing unit. In particular, in accordance with the present process, the temperature of the interior surface of the flash line is adjusted to a temperature which is equal to or higher than the softening temperature of the polymer passing through said flash line whereby said temperature is higher in a first half of the length of the flash line than in the remaining length of the flash line.
