The largest 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 peaking, 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, 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 State Pipe Network Group actively promotes the localization of core equipment and the application
of independent innovative technologies.
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 use of domestic independent innovation technology, with remote one-key start-stop and comprehensive one-key start-stop station functions, the large number of manual on-site operations into a variety of working conditions, multiple modes of established procedures automatic judgment and control, to achieve the unit single start work efficiency from "10 people 1 hour" to "1 person 1 minute" huge transformation, not only further verify the stability and reliability of domestic core equipment and independent innovation technology, for the future comprehensive promotion of related applications accumulated valuable experience.
It has also made positive contributions
to the revitalization of the old industrial base in Northeast China and the promotion of regional economic development.

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