  • PROCESSES FOR REMOVING ENTRAINED PARTICULATES FROM A GAS
    Publication number: 20150306531
    Abstract: In a process for removing entrained particulates from a gas, a chemical reaction may be conducted in a vessel. Conducting the chemical reaction may include suspending particulates in a gas in a fluidized bed in the vessel. A portion of the gas and entrained particulates may be directed to a filter medium and the entrained particulates may be filtered from the gas. Filtering the entrained particulates may include directing the gas from a feed side of the filter medium through the filter medium to a filtrate side of the filter medium and may also include directing at least a portion of the entrained particulates generally tangentially along the feed side of the filter medium to scour the feed side of the filter medium. The particulates may then be directed from the feed side of the filter medium into a dip leg.

  • Arrangements for removing entrained catalyst particulates from a gas
    Patent number: 9168499
    Abstract: An arrangement for removing entrained catalyst particulates from a gas may include a pressure vessel, a filter assembly, and a dip leg. The pressure vessel may contain a fluidized bed of catalyst particulates suspended in the gas. Some of the gas and entrained catalyst particulates may be directed to the filter assembly where the entrained catalyst particulates are filtered from the gas by a filter medium. The catalyst particulates pass generally tangentially along a feed side of the filter medium, where they scour the feed side of the filter medium, and then pass into the dip tube which guides the catalyst particulates away from the filter medium.
