Method and apparatus for removal of heat from an olefin polymerization reactor |
| abstract |
In polymerizing a C2 to C8 olefin, in a polymerization reactor with a reflux condenser (3), a gas mixture (4) withdrawn from the polymerization reactor is first washed (2) before it in reaches the heat transfer surface of the reflux condenser (3) to remove active catalyst particles and polymer particles entrained therein. It is then partially condensed in the reflux condenser (3) to obtain a condensed liquid (7) for return to the polymerization reactor whereby the heat generated in the polymerization reactor is efficiently removed without causing any clogging of pipes. The uncondensed gas is returned to the reactor via a compressor. The washing means is a gas-liquid contactor such as a tray, disc scrubber or cyclone scrubber, or spray tower and can be in the lower portion of the condenser. The washing is preferably by countercurrent contact of the gas mixture with condensed liquid obtained in the condenser and/or solvent. <IMAGE> |
