Ten years of significant progress in chemical engineering technology – praising the prosperity and strength of modern China. This is just a starting point; more participation will make things even more interesting. With you here, HaiChuan becomes even better. [Ten years of progress in chemical engineering equipment] – continuous updates and summaries available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html. Enhance quality awareness and promote high-quality development. -----------------------------------------Recently, the expansion unit at Qiulin Gas Gathering Station in the Southwest Oil and Gas Field successfully completed its operational tests, achieving 110% of the expected performance levels and thus exceeding the acceptance criteria. The successful operation of this type of equipment marks the official entry into practical use of CNPC’s first patented pressure-driven power generation system based on the natural gas J-T valve dehydration and dehydrogenation process. It also signifies that the 711th Research Institute of China State Shipbuilding Corporation has successfully overcome the key technical challenges related to power generation using natural gas at pressures above 6 MPa. A product portfolio suitable for various natural gas pressure reduction power generation applications has thus been established, representing an important step forward in the field of energy-saving and environmentally friendly equipment. Excess pressure generator sets use expanders to reduce the pressure of natural gas; the deployment of such equipment can significantly lower the overall energy consumption of natural gas stations. By recovering the pressure energy lost due to decompression through the original J-T valve, it is possible to reduce the outlet pressure of the compressors in the station, thereby lowering the energy consumption of those compressors. Taking the commissioning of the equipment in this project as an example, users will reduce compressor energy consumption by approximately 1.7 million kWh per year; the saved energy is equivalent to 811.95 tons of standard coal per year, resulting in a reduction of 1,414.8 tons of carbon dioxide emissions per year. This translates into direct economic benefits of around 3 million yuan.

【Pressure Difference Power Generation Project at Rongshan Gas Transmission Station of CNPC Southwest Oil and Gas Field Company】 In December 2021, the pressure difference power generation project at Rongshan Gas Transmission Station of CNPC Southwest Oil and Gas Field Company was officially put into operation. Natural gas pressure difference power generation technology is an innovative low-carbon energy technology. Its principle involves feeding high-pressure natural gas into an expander to generate work; the energy from the pressure difference is converted into mechanical energy, which is used to drive a generator to produce electricity and cold energy. The natural gas after pressure reduction is then supplied for use by users. A differential pressure power generation device does not consume natural gas during the power generation process, and produces no wastewater, exhaust gases, or solid waste during operation, thus causing no environmental impact; it is a clean and efficient distributed energy source. At present, the expansion and renovation project of the Rongshan gas transmission station has been completed. The daily gas transmission capacity has increased from 2.5 million cubic meters to 4 million cubic meters, while the outlet pressure has risen from 1 MPa to 1.5 MPa, resulting in a pressure difference of over 0.8 MPa between the station and the users. This facilitates the transmission of more \"green electricity\" and generates greater benefits.
