Apparatus and process for improved pumping polymerization in suspension in reactors of cycle.

摘要

"Pumping apparatus and process for improved polymerization in suspension in the reactor cycle".The polymerization process of olefin and the apparatus where a suspension fluid comprising monomer, diluent and catalyst is circulated in a continuous loop reactor by two or more pumps (100, 102).The process and the apparatus to operate the reaction with solid content significantly increased in the suspension fluid in circulation.In a preferred mode, the suspension fluid is circulated by two pins (22a)22b) arranged so that the propellant in the direction of the current (22a) benefits from the rotational energy transmitted by the engine against the current (22b).A polymerization process of olefin reactor operating with higher solids due to the movement more aggressive, improved efficiencies, particularly in reactors of large volumes.
