Abstract
A method for removing CO from a CO -containing hydrocarbon asset. The process includes contacting a CO -containing hydrocarbon asset with an aqueous liquid stream at an underwater location so that at least a portion of the CO in the hydrocarbon asset is dissolved into the aqueous liquid stream, creating a CO -depleted hydrocarbon asset and a CO -enriched aqueous stream. The CO -enriched aqueous stream is separated from the hydrocarbon asset. Finally, the CO -enriched aqueous stream is disposed of in at least one of a marine environment, a terrestrial formation, or combination thereof.
