Shenyang Blower Group Co., Ltd. reported last week that the company is a propylene refrigeration compressor unit developed by Sinopec Zhenhai Refining & Chemical Company's one million-ton ethylene plant. It passed the factory acceptance of the Sinopec acceptance committee and will be shipped in the near future. The overall technology of the unit reached the international advanced level and filled the domestic gap. This is another major breakthrough made by Shengu Group in the design and manufacture of large-scale centrifugal compressors after successfully developing the Tianjin Petrochemical million tons ethylene cracking gas compressor unit.
This set of propylene compressors for Zhenhai Refining and Chemical Co., Ltd. is the largest of its kind, and its design and manufacturing technology has long been monopolized by a few large foreign companies. Shengu Group has carried out many innovations in the optimization design of the whole machine, such as adopting newly-developed software to perform overall optimization design and calculation, satisfying the design requirements for the operating conditions of each process section of the machine, and having large flow adjustment range and perfect levels Performance matching; a model-level numerical platform is built in the pumping volute chamber, its flow characteristics and the characteristics of the two gas mixtures are studied, and the design model level is numerically calculated and optimized; the numerical simulation method is used to analyze the flow field of the exhaust chamber. From the structural optimization, improve the unit's operational stability and reliability. In addition, they also adopted Class II tests stipulated in the ASME-PTC10 standard, compiled aerodynamic performance test program, conducted thermal performance tests of substitute gases, and verified product design, processing and manufacturing quality and aerodynamic performance indicators, providing users with satisfaction. product.
The experts of the acceptance committee unanimously agreed that the performance index of the propylene compressor unit of the million-ton ethylene plant has reached the requirement that the power deviation of the complete machine in the technical agreement is not more than 2% of the design power, far lower than the 4% specified by the ASME PTC-10 standard. After more than four hours of continuous operation, the unit has an operating vibration amplitude of less than 11 microns, which is lower than the 25.4 microns specified in the technical agreement and the API 617 standard. The overall technology of the unit has reached the international advanced level, breaking the long-term dependence on imports of such products.
With the continuous development of cracked gas compressors and propylene refrigeration compressors for the million-million-ton ethylene plant based on China's large-scale ethylene projects, and the successful development of ethylene compressors, the “three machines†for the million-million-ton ethylene plant have been successfully developed. We have made breakthroughs in the representation of key technologies and core equipment, which has further enhanced our ability to automate large-scale petrochemical plants and gradually reached the international advanced level.
