Selection of the compressor’s compression capacity

I’m seeking advice from everyone regarding the operating capacity of compressors, with the main concern being the impact of moisture content in the gas on the compressor’s performance. The compression medium is CO2 gas; the inlet pressure is at atmospheric pressure, the temperature is 25°C with 100% humidity, and the compression capacity is 22 bar ； The customer requires a compression capacity of 700 kg per hour. Our conventional compressors are designed based on capacity in m3/min; so how can this be converted to kg/h? The density of CO2 gas is 1.842 kg/h. The pressure ratio found online is equal to the volume ratio ； I checked, and the saturated vapor pressure at 25°C is 0.003169 MPa ； The atmospheric pressure is 0.101325 MPa; based on this calculation, only 3.12% of the volume is occupied by water. This is a very small proportion, and it should have little impact on the capacity of the compressor. However, for everyday use, it doesn’t seem quite right; I would appreciate some guidance from those with more experience.
