TH26857EX - 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 suspension of the pre-polymer particles is 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 Continuously to a post-asset set containing a gas extraction device (10), a place for separating olefinic monomers that Not yet reacted by being dissolved, most things that should be used are 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 purpose of making highly-resistant thalachite concentrate suspensions can It is applied in a process where the reduction of the pre-polymer build-up makes it possible to achieve stable quality pre-polymer. That and have the required size
