On November 18, the compression units at the Shenyang Liaoluo Compressor Station were put into operation, marking the full completion and activation of China’s largest natural gas hub compressor station in the Northeast region. The daily natural gas transmission capacity has increased to around 100 million cubic meters. The 4 17-megawatt compressors put into operation this time were independently designed and manufactured in China, resulting in a comprehensive cost reduction of about 30% compared to imported equipment ； In terms of unit control, domestic independently developed technologies are employed, offering remote one-click startup and shutdown of the machine, as well as comprehensive one-click startup and shutdown of the entire station.
The Shenyang Link Compressor Station is an important hub for natural gas transmission pipelines such as the Qinshen Line, Hashen Line, Dashen Line, and the China-Russia East Line. The operation of this compressor unit will further enhance the peak regulation, pressure control, and flexible allocation capabilities of the pipeline network system in the Northeast region. At present, the annual gas transport capacity of the China-Russia East Route pipeline is around 15 billion cubic meters; it transports natural gas through provinces such as Heilongjiang, Jilin, and Liaoning to regions including Beijing-Tianjin-Hebei, the Bohai Rim area, and the Yangtze River Delta. As planned, it will increase year by year from 22 billion cubic meters in 2023 to 30 billion cubic meters in 2024 and 38 billion cubic meters in 2025.
The Shenyang Interconnection Compressor Station is located in the southern part of Dalamama Township, Xinmin City, Shenyang Province, Liaoning Province. It is the fifth compressor station on the China section of the China-Russia pipeline, and it is interconnected with the existing Qinshen, Dashen, and Hashen natural gas pipelines. The station is equipped with four sets of 17MW electric-driven compressor units. According to the design specifications, the outlet pressure of the compressors at the Shenyang Interconnection Compressor Station is set at 8.7 MPa during summer conditions, 9.6 MPa on an average annual basis, and 9.8 MPa during winter conditions. The commissioning of the compressors at this station is of great importance, as it determines whether the gas demand of various main and branch natural gas pipelines can be met, and it attracts close attention from the **pipeline network management. The 4 compressors put into operation this time were designed and manufactured by Shenyang Blower Group, resulting in a comprehensive cost reduction of about 30% compared to imported equipment ； In terms of unit control, domestic independently developed technologies are employed, offering remote one-button start/stop functions for the units as well as comprehensive one-button start/stop functions for the entire station. This enables a large number of manual on-site operations to be replaced by automatic judgment and control based on predefined procedures under various operating conditions and modes. As a result, the efficiency of starting a unit has improved dramatically, from \"10 people taking 1 hour\" to \"1 person taking 1 minute\". This not only further verifies the stability and reliability of domestically produced core equipment and independently developed technologies, but also provides valuable experience for the widespread adoption of such technologies in the future. It also makes a positive contribution to reviving the old industrial bases in the Northeast and promoting regional economic development.
