First depropanizer is installed at the Amur Gas Processing Plant

The first propane column (depropanizer) has been successfully installed at the first start-up complex of the Amur Gas Processing Plant (GPP).


The equipment is designed for production of commercial propane fraction and is an integral part of the gas fractionation unit which divides a wide fraction of light hydrocarbons into propane, butane and pentane and hexane fractions. The weight of the depropanizer is 200 tons, the length of the column is 54.3 m. In total, three depropanizers will be installed at the Amur GPP, one for every two process lines.

Gazprom's Amur Gas Processing Plant will become one of the world's largest natural gas processing plants. Its design capacity will amount 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. The plant will receive the multi-component feed gas from Power of Siberia gas pipeline from the Yakutsk and Irkutsk gas production centres currently built by Gazprom with 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.
