Movement to the East: “Turbokholod” won the contest of OOO “Gazprom Dobycha Irkutsk” for supply of turboexpanders
The victory of “Turbokholod” JSC in the tender of “Gazprom Dobycha Irkutsk” LLC enabled the Russian manufacturer of TDA to join the large-scale East Siberian project for the production, processing and transportation of hydrocarbons to the countries of the Asia-Pacific region.
In 2011, “Gazprom Dobycha Irkutsk” LLC – a 100% “daughter” company of “Gazprom” PJSC started industrial development of the Kovykta gas condensate field (GCF) in the Irkutsk region, the license for development of which is owned by the parent company.
The field was discovered during the Soviet years. It is unique in its kind: it is located in an area with a harsh sharply continental climate on a high-altitude plateau. Despite the complex geological and climatic factors, the Kovykta gas field is considered attractive in the Russian gas production market. The balance gas reserves of the largest field in Eastern Siberia are estimated at 1,900 billion cubic meters
In the next decade, Kovykta (along with the Chayandinsky field in Yakutia, where “Turbokholod” previously delivered 8 ADKG-20 series units) will become the main supplier of the “blue fuel” for gasification of Eastern Siberia and the Far East, as well as for the supply of methane to China via the main gas pipeline “Sila Sibiri”.
In total, during the development of the Kovykta gas processing plant, five integrated gas treatment units (UPKG), a condensate pipeline and a stable condensate shipment terminal will be built.
JSC “Turbokholod” will join the project at the construction stage of the UPKG: the company will manufacture, install and carry out commissioning of 12 modular turboexpanders ADKG-10 with a block of shut-off and control skid valves, develop and provide the customer with design and design documentation, train operators of technological systems to manage the units.
About the process cycle:
Reservoir gas from the wells will be fed to the integrated gas treatment units (UKGP-2, 3, 4), where the gas, pre-cooled in the heat exchangers, will enter the intermediate separator to remove the liquid released during cooling. The gas then flows into the turboexpander, where it expands and cools as it works, and is then fed to a low-temperature separator to remove condensate. At the last stage of preparation, the” drained ” gas will flow into the compressor of the turboexpander, where it is compressed to the inlet pressure of the head compressor station. This process enables to bring the feedstock to the requirements of STO Gazprom 089-2010 on the dew point for moisture and hydrocarbons.
