Investment Committee approves construction of second stage of CGFU in Tobolsk

The Investment Committee of SIBUR has approved a project for expanding the “Tobolsk-Neftekhim” complex for processing natural gas liquids (NGL), one of the products derived from processing associated petroleum gas (APG).

The Investment Committee of SIBUR has approved a project for expanding the “Tobolsk-Neftekhim” complex for processing natural gas liquids (NGL), one of the products derived from processing associated petroleum gas (APG).


The construction of the new line of the central gas fractionation unit (CGFU-2) will enable the processing of a further 2.8 million tonnes of NGL per year. NGL-derived products are used in further petrochemical processes for producing a wide range of plastics and synthetic rubbers.

Propane produced at the “Tobolsk-Neftekhim” CGFU will be supplied to the complex being built next to the “Tobolsk-Polymer” facilities.


The CGFU-2 project is scheduled for completion in late 2014. At present, the company has already completed the basic engineering design, obtained the conclusion of the Directorate General for State Environmental Review (Glavgosexpertise), as well as the required permits to build the facilities.

It is currently in the process of selecting equipment suppliers and general contractors for carrying out the required construction and installation works.

The Design Institute is continuing to develop the engineering documentation for this project.


After the completion of the project, the total output capacity of the “Tobolsk-Neftekhim” gas fractionation units will reach 6.6 million tonnes of NGL per annum. As a result, such a unit capacity will be the largest in Russia and one of the largest in the world.


Since it was put into operation in 1984, the “Tobolsk-Neftekhim” gas fractionation unit has processed about 2 million tonnes of NGL per annum. Since 2005, the production capacities of the gas fractionation unit have gradually increased, reaching 3 million tonnes in 2009, then 3.5 million tonnes in 2010, and finally 3.8 million tonnes in 2011.
The expansion of gas fractionation facilities is part of SIBUR’s programme for developing its gas processing facilities in Western Siberia. This plan envisions an increase in the amount of associated petroleum gas processed, and the design and construction of a new pipeline with a capacity of 8-11 million tonnes per annum to transport NGLs from the Yuzhno-Balyksky Gas Processing Plant (GPP) to the “Tobolsk-Neftekhim” facilities. It also entails the construction of the “Tobolsk-Polymer” complex in Tobolsk, which will produce 500 thousand tonnes of polypropylene per annum, and the implementation of several other infrastructure projects.
