CONTINUOUS GAS PHASE POLYMERIZATION APPARATUS FOR ALPHA OLEFIN

摘要

A continuous gas phase polymerization apparatus for alpha olefin of the present invention comprises: a first polymerization unit for primarily polymerizing a polymer; a second polymerization unit which is connected to the first polymerization unit and secondarily polymerizes the polymer; a gas-solid separation unit, which is formed on an upper side of the second polymerization unit and separates the gas from the solid; a barrier unit, formed on the boundary of the gas-solid separation unit and the second polymerization unit, which includes a liquid barrier fluid which is mixed with the polymer in which the gas is separated by the gas-solid separation unit and moves the polymer, and transfers the liquid barrier fluid mixed with the polymer from the gas-solid separation unit to the second polymerization unit; and a bypass unit which has one end connected to the second polymerization unit and the other end connected to the gas-solid separation unit to transfer the gas reaching the upper portion of the second polymerization unit to the gas-solid separation unit.
