JSC “Cryogenmash” specialists have started the commissioning of the air separation plant (ASP), Amur GCC
29.04.2025
The testing and adjustment of equipment have been started in the compressed dry air production unit.
The commissioning (CW) of the plant is performed in two stages as the construction and installation works are completed. The compressed dry air production system was the first starting the test stage. Specialists inspect the tightness of pipelines, the operability of control valves, filters and assembly units, test APCS, perform the separate tests of dynamic and vessel equipment such as compressors, pumps, dryers, heat exchange sets, distribution and other devices.
"Based on the results of the CW two stages, the comprehensive testing is being performed, in which it is required to verify the operability of equipment, engineering and process systems, the safety of their operation, check and adjust all monitoring and control systems, control and measuring means, protection devices, locks and alarms," said Anton Parfyonov, Chief Expert of Energy Production, Amur GCC. - Comprehensive testing is considered as completed if the main and auxiliary equipment operates without deviations and continuously within 72 hours and reaches maximum workloads.
The ASP at the Amur GCC, which will produce industrial gases (low- and high-pressure nitrogen and air), also includes two cryogenic air separation plants A-23 and a liquid nitrogen storage and gasification system. Testing of these systems within CW is going to be started in June.
All cryogenic equipment is developed and manufactured by "Cryogenmash", the plant near Moscow, which is the leader of the domestic cryogenic engineering industry. All processes at the station are controlled automatically.
"The capacity of the air separation plant concerning the compressed dry air will be 31,200 m3/hr, for low–pressure and high-pressure gaseous nitrogen - 46,000 m3/hr. Cryogenic ASPs A-23 has been developed by Cryogenmash specially for this project and embodies the advanced ideas of Russian cryogenic engineering and, at least, as good as the best world models," said Evgeny Matveev, General Director of JSC "Cryogenmash".
"Facilities such as ASPs are among the most important for any industrial complex, especially such as the AGCC. Technical gases are produced here in a large pressure range, which are widely used both in process operations and are required for the operation of control systems, automation devices and instrumentation, and are used in large quantities during the current and scheduled shutdown repairs," notes Evgeny Karasev, Senior Manager of Energy Production, Amur GCC. Today, compressed dry air is required to start the commissioning at the pyrolysis plants. The first cubic meters of air will be delivered to the plant in April.
In addition to the main Pyrolysis, Polymer and Polyethylene industries, the list of consumers of industrial gases also includes the facilities of utilities.
It is worth reminding that nitrogen at the industrial companies is required to ensure fire safety. Compressed process air is required for the control systems, process automation, pneumatic control systems, cleaning of equipment from coke deposits.
Sergey Ardashev, Director of the Utilities Operational Unit, Amur GCC: "The cryogenic air separation plant (ASP) is a significant component of the entire gas chemical complex – it will provide the Amur GCC with technical gases. The construction of the plant is coming to its logical completion. Thanks to the well-coordinated work of our team, another stage has been taken towards the startup of the entire AGCC."
