TH26857A - Processes and Equipment for Gas Phase Polymerization of Alpha-Olefin - Google Patents

Abstract

The invention involved a process and equipment for the pre-polymerization of alpha-olefins such as ethylene or propylene in gases and equipment with reactive polymerization phase gases. Actuator (5), in which the suspensions of the pre-polymer particles are fed in Hydrocarbons that are liquid saturated to remain continuously. The pre-polymer suspension is prepared in one or more pre-polymerization tubes (14). And get through Continued to a post-asset set containing a gas extraction device (10), a place for the separation of olefinic monomers that Have not been reacted by the solubility, most of which should be used is Use the Post-Retreat Set. A unit that may contain a particle separation device (11) for removing the finest and / or the coarse particles of pre-polymer. From suspensions and / or concentrators (11a) for the solidification of highly-resistant thalachite concentrate suspensions can It is applied in a process where the reduction of pre-polymer deposits can result in stable quality pre-polymer. That and have the required size
