摘要:
A method for preventing or inhibiting fouling in a gas-phase polyolefin polymerization process. The method includes maintaining the inside surface temperature of the process equipment below the dew point temperature of the gas mixture passing through the equipment.
摘要:
There are disclosed polymerization processes and associated apparatuses. The polymerization processes involve both making a polymeric material in a fluidized bed reactor having a feed distributor and catching a spitwad with a spitwad catcher, and the apparatuses are those corresponding to such processes.
