Shenyang Liaison Compressor Station, the largest natural gas hub compressor station in Northeast China, was officially put into operation

On November 18, with four 17 MW compressor units officially put into operation, the daily transmission capacity of Shenyang Liaison Compressor Station, a key national oil and gas infrastructure project built by the National Pipe Network Group, was increased to about 100 million cubic meters, becoming the largest natural gas hub compressor station
in Northeast China.

Shenyang Liaison Compressor Station is an important hub station connecting Qin-Shen Line, Harshen Line, Dashen Line, China-Russia East Line and other long-distance natural gas pipelines
.
The commissioning of the compressor unit will further improve the peak regulation and pressure regulation and flexible allocation capacity of the Northeast Pipeline Network System, and lay a solid foundation for the construction of the "North-South Down" channel, which is dominated by the China-Russia East Route natural gas pipeline and supplemented by the Harshen Line and the Qin-Shen Line, and the increase in the transmission volume of the Northeast Natural Gas Pipeline Network System this winter and next spring, which is of strategic significance for ensuring the daily life and industrial gas consumption of residents along the route, promoting the adjustment of
industrial structure and energy structure optimization along the route, and achieving the goal of "carbon peak and carbon neutrality".

The four compressors put into operation this time are designed and manufactured by Shenyang Blower Group, which reduces the comprehensive cost of imported equipment by about 30%.

In terms of unit control, the compressor adopts domestic independent innovation technology, with remote one-key start-stop and comprehensive one-key start-stop station functions, transforming a large number of manual on-site operations into automatic judgment and control of established programs in various working conditions and modes, realizing the huge transformation of the single-start work efficiency of the unit from "10 people 1 hour" to "1 person 1 minute", further verifying the stability and reliability of localized core equipment and independent innovation technology, and accumulating valuable experience for the comprehensive promotion of related applications in the future.
It has also made positive contributions
to the revitalization of the old industrial base in Northeast China and the promotion of regional economic development.

During the construction of the compressor station, the National Pipe Network Group has carried out a lot of technical research in the independent design, independent construction, equipment localization, high system integration, remote control and other aspects of the compressor station control system, achieved major breakthroughs, and carried out innovative exploration on the construction and safe operation of unattended stations of oil and gas pipelines, and simultaneously carried out the improvement of the compressor unit control system to improve the stability and reliability of the unit operation, providing technical support
for the construction of intelligent pipelines and intelligent pipe networks.
