Noyabrsky GPP

Muravlenkovsky GPP

The Muravlenkovsky GPP was designed to handle 2.14 bcm/year of associated gas.

Muravlenkovsky gas processing section

The Muravlenkovsky gas processing section receives associated gas for processing, including compression, drying and extraction of liquid hydrocarbons (NGLs). The dry stripped gas is then pumped into the Urengoy – Chelyabinsk long-distance pipeline or to the Surgut GPP, while NGLs are fed into the Novyy Urengoy – Surgut Condensate Stabilization Plant product pipeline.

The associated gas comes from the Kholmogor CS, the Kogalym GCS and the Muravlenkovskoye, Sutormin and Sugmut fields via four 500 mm gas lines.

The currently operating 1st train of the Muravlenkovskoye gas processing facility has a capacity of 1.073 bcm/year.

Kholmogor CS

The Kholmogor compressor station was designed to handle 535 mcm/yr and became operational in 1985. The gas come from the Kholmogor, Karamov, Zapadno-Noyabrskoye and Pogranichnoye fields, and is pumped from the station to the Muravlenkovskoye GPP.

Vyngayakhin CS

The Vyngayakhin compressor station was designed to handle 535 mcm/yr and became operational in 1991. It forms part of the Noyabrskgazpererabotka branch of SiburTyumenGaz and its function is to receive, compress and dry associated gas from the “Zapolyarneft” oil production unit to prepare it for onward transmission to the Vyngapurov CS.

The Vyngayakhin compressor station is fed by associated gas from the Vyngayakhin, Vostochno-Vyngayakhin and Novogodneye fields, which is then pumped to the Vyngapurov CS.

Vyngapurov CS

The Vyngapurov CS was designed to handle 1.440 bcm/yr and became operational in 1989-1990.

It forms part of the Noyabrskgazpererabotka branch of SiburTyumenGaz and was built to compress and dry associated gas from the first stage of separation at the Vyngayakhin station and from the Vyngapurov field to prepare it for onward transmission via the long-distance Urengoy - Chelyabinsk gas line.

Until 1989 the Muravlenkovsky GPP and the Noyabrsk gas processing enterprise formed a separate branch of Sibneftegazpererabotka. Following a restructuring on 1st January 1999 the Muravlenkovsky GPP was incorporated into the Muravlenkovskoye gas processing unit within the Noyabrsk GPP, which is a branch of Sibneftegazpererabotka (and from 1st June 2000, a branch of Sibur-Tyumen).

The MGPP comprises two associated gas processing trains with a capacity of 1.073 bcm/yr each.

The Muravlenkovsky GPP was brought on stream in December 1987 with the commissioning of the first gas compression and drying train. The second train became operational in the autumn of 1989, but was closed down in 1993 following a drop in gas deliveries, and was later cannibalized due to a lack of funds to purchase spare parts for train No.1.

In 1992, with the help of the VNIPIgazpererabotka institute (Krasnodar), a stable gasoline production line was designed and built. This was a priority project at that time in view of the strong market for gasoline and it enabled the enterprise to achieve maximum extraction of heavy fractions. It also ensured that the hydrocarbon dew point specifications in the GOST 5140-93 state standard were met.

In August – September 2002 SIBUR adopted a plan of action to boost extraction of target components from the gas to 93%. In February 2004, following an upgrade involving the installation of a propane refrigeration unit and a turboexpander, the component yield reached 86%, and in April 2004 this was further increased to 91-92%.

The stable gasoline storage facility has a capacity of 600 cu m.
