Gas treating method and apparatus
First Claim
1. An apparatus for treating a contaminated gas comprising:
- a high-pressure vessel comprising a pool of contaminant-absorbing liquid comprising a glycol;
a manifold for introducing the contaminated gas into the vessel, wherein the manifold introduces the gas into the vessel below the top level of the pool of contaminant-absorbing liquid;
at least one flow disperser contained within the vessel and positioned above the manifold and beneath the level of the pool of contaminant-absorbing liquid; and
one or more spray nozzles contained within the vessel and positioned above the level of the pool of contaminant-absorbing liquid, operable to introduce contaminant-absorbing liquid counter-current to the flow of contaminated gas in the vessel.

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.
