APPARATUS FOR CONTINUOUS GAS PHASE ALPHA OLEFIN POLYMERIZATION

摘要

The present invention relates to a continuous gas-phase polymerization apparatus for alpha olefin, comprising: a first polymerization unit for firstly 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 gas and solid; a liquid barrier which is formed on a boundary of the gas-solid separation unit and the second polymerization unit, and is mixed with a polymer where gas is separated by the gas-solid separation unit, and moves the polymer; a barrier unit which transfers the liquid barrier mixed with the polymer from the gas-solid separation unit to the second polymerization unit; and a by-pass unit in which one end is connected to the second polymerization unit, and the other end is connected to the gas-solid separation unit, and which transfers the gas reaching the upper portion of the second polymerization unit to the gas-solid separation unit.
