In May 2014, CCPGE successfully completed the acoustical, mechanical and torsional studies of DGY 630 BOG compressor packages per API 618, and FEA for temperature, stress and deflection distributions of DGY 630 BOG compressor cylinders. This is the first compressor package designed in China to operate with suction temperature ranging from below -160°C to above 0°C, and discharge temperature from below 0°C to over +150°C. The success of this project demonstrates the proficiency of CCPGE in API 618 design of compressor packages as well as in structural design of advanced compressor components.
