Abstract:
A process of recovering high pressure carbon dioxide from a gas, said process comprising:a) providing a carbon dioxide-containing gas at high pressure; b) providing a liquid solvent, said solvent being capable of absorbing the carbon dioxide present in the gas; c) contacting the high pressure carbon dioxide-containing gas with the liquid solvent in a gas-liquid contactor under high pressure; d) separating the carbon dioxide-laden solvent from the carbon dioxide depleted gas; e) heating the carbon dioxide-laden solvent; f) contacting the heated carbon dioxide-laden solvent with an inert stripper gas, wherein the stripper gas is at pressure greater than about 100 psi, said contacting under conditions such that the stripper gas strips carbon dioxide from the solvent; and g) separating the stripper gas comprising the carbon dioxide from the heated solvent.
