METHOD AND APPARATUS FOR DISCHARGING A POLYMER FROM A GAS-PHASE REACTOR

METHOD AND APPARATUS FOR DISCHARGING A POLYMER FROM A GAS-PHASE REACTOR

Process and apparatus for discharging polyolefin particles from a gas-phase polymerization reactor of a pressure from 1.0 MPa to 10 MPa to a discharge vessel of a pressure from 0.1 MPa to 1.0 MPa wherein the discharging is carried out discontinuously through at least two discharge lines in which the...
