Compression of carbon dioxide containing fluid
First Claim
1. A method of pressurizing a fluid comprising carbon dioxide, the method comprising:
- 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, the fluid being compressed to a pressure within the range of 9-12 MPa; and
cooling the compressed fluid to a temperature above the critical temperature of carbon dioxide to produce a supercritical fluid; and
wherein the fluid is compressed and cooled such that the compressed and cooled fluid is a one phase supercritical fluid.

11. A method of pressurizing a fluid comprising carbon dioxide, the method comprising:
-
obtaining the fluid from a unit for removing carbon dioxide from a process gas, the fluid comprising at least 80 mol-% carbon dioxide and at most 90 mol-% carbon dioxide; 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; and wherein the fluid is compressed and cooled such that the compressed and cooled fluid is a one phase supercritical fluid.
