Could an expert help calculate this? With an annual transportation volume of 300,000 tons, is it necessary to use a centrifugal compressor?

Based on the parameters specified by the poster: gas medium: CO2, inlet pressure: 0.13 MPa, temperature 30℃； Outlet pressure: 15 MPa, temperature 50°C. 300,000 tons per year, which is approximately 34 tons per hour. Under standard conditions, the mass of 1 mole of CO2 is 44 grams, and its standard volume is 22.4 liters. 1 ton equals 1,000,000 grams; therefore, the volume of 1 ton of carbon dioxide is 1,000,000/44 × 22.4 = 509,090 liters, which is equivalent to 509 cubic meters. So the displacement is 34*509 cubic meters per hour = 288.43 cubic meters per minute. By checking some domestic centrifugal compressor listings, it is found that Option 1 is available: Manufacturer: Shenyang Blower Factory ； Displacement: between 3.5 and 1600 cubic meters per minute ； Gas medium: various gases ； Pressure: within 70 MPa. Power: 630 to 2000 KW ； Series: BCL, 2BCL, 3BCL type vertical section compressors. Option 2: BCH, PCH, and POB type vertical partial compressors manufactured by Shanghai Blower Factory. Therefore, the poster can choose Option 1: Compression using a single centrifuge can meet the requirements regarding outlet pressure, flow rate, medium, etc

1. If calculated at 8,000 hours per year, the average hourly flow rate is 37.5 tons per hour； 2. The centrifugal compressor seems to refer to mass flow rate; there is a minimum value for the mass flow rate at the inlet of the final stage ； 3. There is another issue: what is the allowable range of fluctuation in the air supply for centrifugal compressors? Sometimes the operating conditions are not that stable ；

Both the second and third issues can be resolved by adjusting the circuit.

Both the second and third issues can be resolved by adjusting the circuit. What was said on the third floor is correct. The traffic volume should be within that range.

And the flow rate I calculated is at standard atmospheric pressure
