Development of low-temperature centrifugal propylene refrigeration compressor
A low-temperature centrifugal propylene refrigeration compressor was developed and designed based on the propylene refrigeration unit in one coal chemical plant of Shengu Group Co.,Ltd.,and the best compressor design solution was obtained by optimizing the aerodynamic scheme,designing the casing structure,optimizing the impeller structure,improving rotor dynamics design,optimizing the dry gas seal design at the shaft end and optimizing the system control scheme.The designed compressor could meet such process requirements as high flow rate,high pressure ratio and high performance.
