  • Gas treating method and apparatus
    Patent number: 8894758
    Abstract: A method and apparatus for treating natural gas comprises a contactor having a manifold for spreading gas in the contactor vessel, a plurality of perforated plates above the manifold, a spray system for spraying a treating liquid into an upwardly rising column of gas and a liquid level controller for maintaining the treating liquid above the perforated plates. Gas and liquid from the contactor pass through a cooler and are then separated. A treating liquid regeneration system receives the treating liquid and flashes the liquid at low pressure to separate hydrocarbon gases, hydrocarbon liquid and treating liquid. The treating liquid is regenerated by heating and flashing off contaminant gases and is ultimately redelivered to the contactor.
    Type: Grant

  • Method for treating contaminated gas
    Patent number: 8388739
    Abstract: A method for treating natural gas using a vessel having a manifold for introducing gas in the vessel, a flow disperser above the manifold that prevents channeling of the gas, a spray system for spraying a treating liquid into an upwardly rising column of gas and, optionally, a liquid level controller for maintaining the level of a pool of treating liquid above the flow disperser.
