  • Method for feeding a fluid to a gas phase polymerization reactor
    Patent number: 10792637
    Abstract: A fluid is fed into a polymer bed of a fluidized bed gas phase polymerization reactor by introducing the fluid into the polymer bed through a distributor protruding into the fluidized bed zone of the reactor and terminating with a discharge end positioned so that the following equation is fulfilled: d/D>0.002 wherein d is the distance of the distributor's discharge end from the wall of the reactor, and D is the diameter of the reactor in the fluidized bed zone.
    Type: Grant
    Filed: December 15, 2017
    Date of Patent: October 6, 2020
    Assignee: Basell Poliolefine Italia S.r.l.
