Amur Gas Processing Plant connected to Power of Siberia pipeline

BLAGOVESHCHENSK. May 4 (Interfax) - The Amur Gas Processing Plant has now been connected to the Power of Siberia gas pipeline, which supplies gas from Russia to China.

The Gazprom Group's Gazprom Pererabotka Blagoveshchensk LLC said first process line commissioning at the plant was under way. "The plant has been connected to the Power of Siberia trunk gas pipeline. All four tie-ins of the commercial and feed gas pipelines have been completed," the company said.

Feed gas is now supplied to the feed gas dehydration and treatment unit at process line 1, and the equipment is being set up. Preparation of Ladoga gas pumping unit (GPU) 1 for gas reception and hot start have been completed at the booster compressor stations; alignment and cold start of Ladoga GPU 2 are underway.

Preparation for reception of dehydrated gas is being completed at the ethane, NGL and nitrogen and helium mix unit. Functional tests of the equipment are being carried out at the units of process line 1 simultaneously.

The first three spherical tanks of the product and feed area of the Amur Gas Processing Plant are ready for operation. Air is supplied to the mains at the nitrogen and air station, and preparations are being made for the supply of nitrogen to the mains. Main construction and installation at the water treatment facilities have been completed, and commissioning at the water treatment plant has begun.

The Amur GPP is 75.1% complete.

The Amur Gas Processing Plant is being built adjacent to the Power of Siberia pipeline on the border with China to separate valuable chemical components from feedstock for export. The gas supplied via the Power of Siberia pipeline is separated and purified at the plant by cooling it to temperatures close to liquefaction temperature.

The Amur GPP will be one of the largest natural gas processing facilities in the world. The design capacity of the plant will be 42 billion cubic meters of gas per year. The GPP will include the world's largest helium production capacity, up to 60 million cubic meters per year.

The plant will consist of six process lines. The first two are scheduled to be commissioned in 2021. The remaining lines will be commissioned sequentially through the end of 2024. The plant should thus reach its full design capacity by 2025.

In addition to natural gas and helium, the GPP will produce ethane, propane, butane, and pentane-hexane fractions.

The investor and client of the project is Gazprom Pererabotka Blagoveshchensk LLC. SIBUR group's NIPIGAS is the general contractor
