A joint venture of Russian conglomerate PJSC Sibur Holding, Moscow, and PJSC Gazprom Neft, St. Petersburg, have commissioned the newly built Yuzhno-Priobskiy gas processing plant (Yuzhno-Priobskiy GPP) in Western Siberia’s Khanty-Mansi Autonomous Area.
Designed by Sibur subsidiary NIPIgazpererabotka (Nipigaz), Moscow, the Yuzhno-Priobskiy GPP, which began construction in February 2014 based on the Yuzhno-Priobskaya compressor station, entered operation on Sept. 3, Sibur and Gazprom Neft said.
With a capacity to process 900 million cu m/year of associated petroleum gas (APG), the plant also will have a liquids-recovery rate that exceeds 95%, the companies said.
Sibur and Gazprom Neft said they expect processed APG from the plant to generate about 340,000 tonnes/year of NGLs and 750 million cu m/year of dry-stripped gas.
The Yuzhno-Priobskiy GPP comes as part of an initiative to develop a petrochemical cluster in Western Siberia under the Russian government’s gas and petrochemical industry development plan through 2030, the companies said.
Reconstruction of a pipeline for the supply of dry-stripped gas that connects to the Khanty-Mansiysk natural gas pipeline was executed concurrently with construction of the new processing plant to transport gas supplies to a gas-turbine power plant at the Yuzhno-Priobskoye field for power generation, as well as to the city of Khanty-Mansiysk and Khanty-Mansiysk District to meet domestic gas supply needs, Gazprom Neft said in an Apr. 27 release.
Infrastructure also was constructed to enable transportation of NGLs from Yuzhno-Priobskiy GPP to Sibur’s processing operations at Tobolsk in Western Siberia’s Tyumen region (OGJ Online, July 14, 2015; Feb. 20, 2015).
All supporting infrastructure was due to be in place before start-up of Yuzhno-Priobskiy GPP, Gazprom Neft said.
As part of the JV’s agreement, Gazprom Neft will supply APG from Yuzhno-Priobsky field to Yuzhno-Priobskiy GPP on a long-term basis, with Sibur to pay for half of the volume, the companies said in a late-December 2013 release.
The parties additionally agreed that SIBUR will its share of dry gas from APG processed at the new plant to Gazprom Neft and, in turn, purchase Gazprom Neft’s share of NGLs.
