PROCESS FOR ETHYLENE POLYMERIZATION WITH IMPROVED SLURRY PUMP PERFORMANCE Russian patent published in 2019 - IPC B01J19/18 C08F2/01 C08F2/18 

Abstract RU 2685642 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of ethylene polymerization. Method comprises: polymerising monomers in a reactor comprising baffle walls, first suspension feed pipeline to return cooled suspension from cooler, and optionally second suspension feed pipeline to transfer reactor suspension from previous reactor from cascade of polymerisation reactors. Upper part of the baffle plate, the first unloading end of the supply pipeline and the second pipeline of suspension supply are located below the level of liquid medium in the reactor.

EFFECT: technical result consists in creating a method for suspension polymerisation of ethylene with high output of the pump for feeding catalyst suspension due to its smaller clogging.
