Why choose two-stage compression? Two-stage compression uses the pressure ratio to design the inter-stage pressure, so each stage of compression needs to have a much lower compression ratio compared to single-stage compression. The leakage between the rotors is greatly reduced, leading to improved volumetric and adiabatic efficiency, resulting in increased gas production during compression. With the same power, two-stage compression can achieve a gas production rate up to 15% higher than single-stage compression, resulting in energy savings of up to 15%.
