The present invention relates to a method of pressurising a fluid comprising carbon dioxide, the method comprising: obtaining the fluid from a unit 5 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 1 for pressurising a fluid comprising carbon dioxide, the apparatus comprising: means 4 for obtaining the fluid from a unit 5 for removing carbon dioxide from a process gas; means 6 for compressing the fluid to a pressure above the critical pressure of carbon dioxide; and means 7 for cooling the compressed fluid to a temperature above the critical temperature of carbon dioxide to produce a supercritical fluid. |
