Abstract: A method for drying a wet CO2 rich gas stream from an oxy-combustion process that includes: compressing the wet CO2 rich gas stream to a drying process operating pressure, cooling the wet CO2 rich gas stream in at least one cooler, alternately drying the wet CO2 rich gas stream in at least one dryer which contains at least one desiccant bed and regenerating the desiccant bed by conducting a heated regenerating gas through the dryer in opposite direction to the flow direction of the wet CO2 rich gas stream, separating the dried CO2 rich gas stream in a purification process to a purified CO2 gas stream and a waste gas stream rich in nitrogen and oxygen, whereby the waste gas stream rich in nitrogen and oxygen is used as regenerating gas, and subsequently to the regeneration the dryer is purged at least once by a pressurized CO2 rich gas stream conducted from the compressor, and whereby the dryer is charged up to the drying process operating pressure with a pressurized CO2 rich gas stream conducted from the compressor before each drying process.
