The first domestic stripping gas compressor for large-scale LNG production successfully passed tests

On March 1, 2025, in Russia cryogenic tests of the first instance of a domestic stripping gas compressor (BOG) for large-scale production of liquefied natural gas (LNG) conducted successfully.

The compressor based on 54GC-398/1.1-47 compressor unit was developed by specialists of NIITurbokompressor and manufactured at Kazancompressormash (part of HMS Group) as part of the import substitution program for key equipment for large-scale LNG production. The unique low-pressure casing design ensures reliable compressor operation at extremely low (cryogenic) fluid temperatures.

Cryogenic tests were conducted at the test bench of the industry's Scientific Research Institute of Electrophysical Apparatus named after D. V. Efremov (NIIEFA) - one of the leading institutes of the nuclear industry, which is part of Rosatom's structure. During the tests at the up to -165 ⁰С temperature of the pumped medium at compressor inlet all controlled operating parameters were successfully confirmed.

The designed 10 MW compressor unit is intended for compression of stripping gas as part of a prospective domestic large-scale LNG plant.

In March 2025, it is planned to install the compressor on the test bench of Kazancompressormash for gas dynamic tests on a closed circuit using model gases.
