  • Installation for gas-phase polymerisation
    Patent number: 8143358
    Abstract: Installation for the gas-phase polymerization of at least one olefinic monomer, comprising a horizontal stirred reactor (1) consisting of an undivided space, provided with a number of gas feeds (13a-13) in the bottom section of the reactor (1) and a number of liquid feeds (7a-7) in the top section of the reactor (1) and at least two gas outlets (9, 11) at the top of the reactor (1), the installation being provided with means (43, 45) to regulate the discharge capacities of the gas outlets.
    Type: Grant

  • Fluidized bed reactor with asymmetric gas inlet
    Patent number: 6506855
    Abstract: Process for polymerizing one or more olefinic monomers in a fluid-bed reactor which is bounded at the bottom by a gas-distributing plate containing apertures, comprising the supply of a gas to the reactor through the gas-distributing plate and optionally the supply of a liquid to the reactor, in which the average rate at which the gas is supplied to the reactor is higher in a first part of the gas-distributing plate whose area equals half that of the gas-distributing plate than the average rate at which the gas is supplied in a second part covering the area of the gas-distributing plate that lies outside the first part and reactor suitable for this process.
