Method for Treating Contaminated Gas
First Claim
Patent Images
1. A method for treating contaminated gas comprising:
- introducing a contaminated gas into a high pressure vessel comprising a pool of contaminant-absorbing liquid, wherein the contaminated gas is introduced through a manifold at a level below the top level of the pool of contaminant-absorbing liquid;
dispersing the contaminated gas through a flow disperser wherein the flow disperser is positioned in the vessel between the manifold and the top level of the pool of contaminant-absorbing liquid and is operable to prevent channeling of the contaminated gas; and
spraying the contaminant-absorbing liquid from a position above the level of the pool of contaminant-absorbing liquid, wherein the contaminant-absorbing liquid moves in a direction opposite to the direction of flow of the contaminated gas.

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.

8. A method for treating contaminated gas comprising:
-
introducing a contaminated gas into a high pressure vessel comprising a pool of contaminant-absorbing liquid, wherein the contaminated gas is introduced through a manifold at a level below the top level of the pool of contaminant-absorbing liquid; dispersing the contaminated gas through a first perforated plate wherein the perforated plate is positioned in the vessel between the manifold and the top level of the pool of contaminant-absorbing liquid and is operable to prevent channeling of the contaminated gas; and spraying the contaminant-absorbing liquid from a position above the level of the pool of contaminant-absorbing liquid, wherein the contaminant-absorbing liquid moves in a direction opposite to the direction of flow of the contaminated gas. - View Dependent Claims (9, 10, 11, 12)

15. A method for treating contaminated gas comprising:
-
establishing a pressure of at least 800 pounds per square inch (psi) over atmospheric pressure within a high pressure vessel establishing a pool of contaminant-absorbing liquid within the vessel; introducing a contaminated gas into the vessel, wherein the contaminated gas is introduced through a manifold at a level below the top level of the pool of contaminant-absorbing liquid; dispersing the contaminated gas through a flow disperser wherein the flow disperser is positioned in the vessel between the manifold and the top level of the pool of contaminant-absorbing liquid and is operable to prevent channeling of the contaminated gas; and spraying the contaminant-absorbing liquid from a position above the level of the pool of contaminant-absorbing liquid, wherein the contaminant-absorbing liquid moves in a direction opposite to the direction of flow of the contaminated gas.
