The fragrance of rice flowers in August--------------------------------------------- From January 2020 to December 2021, CPE CC Southwest Branch cooperated with Sichuan Air Separation to carry out the research and development of 10 million cubic meters of natural gas expanders. Sichuan Air Separation relied on years of accumulation in the field of natural gas expanders, through research on the reliability of high-power rotors, development of high-efficiency working wheels and press wheels, and research on high-power bearings and shaft seals. Sichuan Air Separation broke through the key technologies of large-scale natural gas expanders and formed a set of design methods with Sichuan Air characteristics. Based on the R&D parameters, the host prototype was designed and produced, and the in-factory test run was completed. The R&D results passed the review of the project team. With the strong support of CPECC Southwest Branch, Sichuan Air Separation Expander Branch continues to carry out research on the 1000×10?Nm3/d natural gas expander auxiliary system based on the capacity construction ground engineering project of Jiaxian block of Shenmu Gas Field in Jidong Oilfield. The demonstration and optimization of auxiliary systems such as the lubricating oil system, sealing gas system, and sealing gas recovery system have been repeatedly carried out, and the entire skid will be shipped from the factory in November 2022. It successfully ran continuously during the joint commissioning of the Jidong Oilfield natural gas processing unit on May 24, 2023. The successful industrial operation of the 1000×104Nm3/d natural gas expander marks the rise of domestic expanders from millions to tens of millions, breaking the monopoly and technical barriers of foreign countries in large and extra-large natural gas expanders. -
