Abstract
A method for removing CO from a gas stream, including methane and CO . The method includes contacting a gas stream with an aqueous stream, so that at least a portion of the CO in the gas stream is dissolved into the aqueous stream, thereby creating a CO -depleted gas stream, having an enriched methane concentration, and a CO -enriched aqueous stream. The CO -enriched aqueous stream is separated from the gas stream. Finally, the CO -enriched aqueous stream is disposed of in at least one of a marine environment, a terrestrial formation or combination thereof.
