    摘要: Process for the polymerization of olefins in a gas phase fluidized bed reactor, by i) passing a fluidizing gas to the reactor to fluidize a bed of polymer particles therein, ii) withdrawing the fluidizing gas from the reactor, iii) cooling all or a portion of the fluidizing gas withdrawn from the reactor to a temperature at which a portion of the components of the fluidizing gas condense to form condensed liquid, and iv) passing condensed liquid and non-condensed components of the fluidizing gas back to the reactor. A reservoir of condensed liquid downstream of the cooling step is provided, and variations in the inventory of the condensed liquid are made in order to control the temperature in the reactor.

    摘要: Process for operating a vertical fixed bed degasser which is continuously fed with an active polymer powder produced by a catalytic olefin polymerization process in a polymerization reactor. The polymerization conditions in the degasser are such that there is produced an additional amount of polymer corresponding to between 0.001 and 0.015 times the amount which entered the degasser. The degassing process includes introducing into the degasser a stripping gas containing principal monomer, with the temperature inside the degasser being the polymerization reactor temperature plus or minus 20° C.
