Abstract:
A method for removing CO2 from a CO2-containing hydrocarbon asset, the method comprising:a) contacting a CO2-containing hydrocarbon asset with an aqueous liquid stream at an underwater location so that at least a portion of the CO2 in the hydrocarbon asset is dissolved into the aqueous liquid stream, creating a CO2-depleted hydrocarbon asset and a CO2-enriched aqueous stream, wherein during contact with the aqueous liquid stream, temperature, pressure, pH, and contacting duration are sufficient to ensure that at least about 90% by weight of the hydrocarbon asset is in a gas phase; b) separating the CO2-enriched aqueous stream from the hydrocarbon asset; and c) disposing of the CO2-enriched aqueous stream in at least one of a marine environment, a terrestrial formation or combination thereof.
