  • Method for producing polyolefin and polyolefin production system
    Patent number: 10941221
    Abstract: A polyolefin production system is provided. The polyolefin production system includes a plurality of gas-phase polymerization tanks configured to polymerize an olefin gas to form a polyolefin, a compressor comprising an inlet and an outlet and being configured to compress a an olefin-containing gas, an individual gas feed line disposed at each of the gas-phase polymerization tanks and configured to guide the gas fed from the outlet of the compressor to each of the gas-phase polymerization tanks, an individual gas discharge line disposed at each of the gas-phase polymerization tanks and discharging the gas from each of the gas-phase polymerization tanks, and a first valve installed in each of the individual gas feed lines.
    Type: Grant
    Filed: August 28, 2018
    Date of Patent: March 9, 2021
    Assignee: SUMITOMO CHEMICAL COMPANY, LIMITED
    Inventors: Satoshi Itoguchi, Naganjaneyulu Suruvu, Shunpei Funaoka
  • Method for producing polyolefin and polyolefin production system
    Patent number: 10683373
    Abstract: A polyolefin production system is provided. The polyolefin production system includes a plurality of gas-phase polymerization tanks configured to polymerize an olefin gas to form a polyolefin, a gas transfer series line connecting the plurality of the gas-phase polymerization tanks to each other in series, a compressor having an inlet and an outlet and being configured to compress an olefin-containing gas, a gas main feed line disposed at the frontmost gas-phase polymerization tank and configured to guide the gas fed from the outlet of the compressor to the frontmost gas-phase polymerization tank, a gas discharge line disposed at the rearmost gas-phase polymerization tank, and a first valve installed in the gas main feed line.
