| 摘要 |
The present invention relates to a process for cooling a polymerization reaction for producing polyolefin comprising the steps of: (a) thermally contacting said polymerization reaction with a cooling fluid such that the cooling fluid removes thermal energy from said reaction, (b) thermally contacting said cooling fluid with a working fluid thereby recovering said thermal energy from said cooling fluid in said working fluid, and (c) thermally contacting the cooling fluid obtained in step (b) with the polymerization reaction thereby cooling said reaction, wherein the working fluid is phase converted thereby providing energy in the form of heat and/or electricity and/or mechanical power back to the polyolefin production process. Said invention also relates to a polymerization process for producing olefin polymers in a reactor, and also relates to a process for energy optimization of energy consumption in a polymerization process and to a polymerization unit. |
