Abstract
The present invention relates to a method of pressurizing a fluid comprising carbon dioxide, the method includes: obtaining the fluid from a unit for removing carbon dioxide from a process gas; compressing the fluid to a pressure above the critical pressure of carbon dioxide; and cooling the compressed fluid to a temperature above the critical temperature of carbon dioxide to produce a supercritical fluid. The invention further relates to an apparatus for pressurizing a fluid comprising carbon dioxide, the apparatus including: means for obtaining the fluid from a unit for removing carbon dioxide from a process gas; means for compressing the fluid to a pressure above the critical pressure of carbon dioxide; and means for cooling the compressed fluid to a temperature above the critical temperature of carbon dioxide to produce a supercritical fluid.
