Feed gas expanders at the first start-up complex of Amur Gas Processing Plant installed

May 20, 2019 00:00Installation of two feed gas expanders has been completed at the construction site of the Amur Gas Processing Plant. The equipment is installed at the cryogenic units for ethane and NGL extraction, nitrogen rejection and production of nitrogen and helium mixture at the first start-up complex of the Amur Gas Processing Plant.

The expanders are designed to cool natural gas by gradually reducing the pressure in order to further extract valuable components. A special feature of this process at the Amur Gas Processing Plant is additional generation of electricity in the process of lowering the temperature, which increases the energy efficiency of gas processing.

Справка

As part of the first phase of construction of the Amur Gas Processing Plant, the first start-up complex will be put into operation in April 2021, which includes two process lines for processing natural gas (each with a capacity of 7 billion cubic meters of gas per year) and one helium purification and liquefaction unit with a capacity of 20 million cubic meters of gas per year.

The Amur GPP is scheduled to reach its full capacity in January 2025. Total design capacity of Amur GPP will amount up to 42 billion cubic meters of gas per year. GPP will also include the world's largest production of helium — up to 60 million cubic meters per year. The Amur Gas Processing Plant is an important link in the process chain of natural gas supply to China via the Eastern route. Multi-component gas will be supplied to the Plant via the Power of Siberia gas pipeline from the Yakutsk and Irkutsk gas production centres, currently developed by PJSC Gazprom as a part of its Eastern gas program.

Gazprom Pererabotka Blagoveshchensk LLC (member of Gazprom Group) is the Investor and Owner of Amur Gas Processing Plant project. Construction is managed by NIPIGAS, a leading Russian centre for engineering, procurement, logistics and construction management (member of SIBUR Group). Peak time for construction will be in 2019 to 2020 when over 25,000 workers will be mobilized to the site.
