US Patent:

8137445, Mar 20, 2012

Filed:

May 12, 2010

Appl. No.:

12/778601

Inventors:

Edwin W. Cash - Westhoff TX, US
Thomas J. Bradley - Victoria TX, US

International Classification:

B01D 47/02

US Classification:

96351, 96329, 261126

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.
