Moisture removal from wet gases
First Claim
1. A method of reducing the water content of a wet gas, the method comprising:
- exposing the gas to an amine-terminated branched polymer solvent, which solvent exhibits an osmotic pressure of about 175 atmospheres or higher so as to remove a substantial portion of the water from the wet gas, resulting in a diluted solvent and a substantially dry gas;
exposing the diluted solvent to carbon dioxide so as to create a phase separation of the solvent from the water;
regenerating the solvent for reuse by desorbing the carbon dioxide by the application of heat; and
directing the regenerated solvent to a new supply of wet gas for water reduction.

Abstract
Methods of reducing the water content of a wet gas are presented. In one case, the method includes exposing the gas to an amine-terminated branched polymer solvent to remove a substantial portion of the water from the wet gas, exposing the diluted solvent to carbon dioxide to phase separate the solvent from the water, and regenerating the solvent for reuse by desorbing the carbon dioxide by the application of heat. In another case, the method includes exposing the gas to a cloud-point glycol solvent to remove a substantial portion of the water from the wet gas, heating the diluted solvent to above a cloud point temperature for the solvent so as to create a phase separation of the solvent from the water so as to regenerate the solvent for reuse, and directing the regenerated solvent to a new supply of wet gas for water reduction.
