At the Kharasavey field of PJSC Gazprom, an power supply complex is being created to supply electricity to construction sites
27 April 2020
The Kharasavey gas condensate field is located in the Yamal-Nenets Autonomous Area, mainly on the land of the Yamal Peninsula and partially in the Kara Sea. By the size of gas reserves (2 trillion cubic meters), it belongs to the unique category.In March 2019, Gazprom began full-scale development of the Cenomanian-Aptian deposits here. The start of production is scheduled for 2023. In the future, it is planned to develop deeper Neocom-Jurassic deposits. The field is being equipped by AO Gazstroyprom, the sole contractor of Gazprom Group enterprises.
As part of the arrangement project, a power supply complex is being created to supply electricity to construction sites. The operating company and the owner of the power supply complex is Allocation Hub LLC.
As the primary source of power supply, six gas-reciprocating power plants (GRPP) MWM 2020 V20 type with a capacity of 2 MW each and two GRPPs MWM 2020 V12 type with a capacity of 1.2 MW each are used. The main consumer of electricity will be a rotational camp for 5,000 people.
The generating facility will also include four mobile automated gas-turbine power plants PAES-2500 with a rated capacity of 2.5 MW each. PAESs are designed to supply electricity to hydraulic flushing units.
The fuel for power supply complex is natural gas produced at the field. Its design parameters on purity, temperature, pressure and flow will be provided by the ENERGAS fuel gas treatment facility (FGTF). The maximum capacity of the facility is 8,000 m3 / h, including: gas consumption for gas reciprocating units – 5,000 m3 / h, for PAES turbines – 3,000 m3 / h.
FGTF is a multifunctional complex of two modules operating in cascade scheme. Module No. 1 is intended for preliminary separation, filtration and pressure reduction of the incoming gas. After the first stage of treatment, the fuel gas enters to module No. 2, where the its final purification, flow measurement, heating and additional pressure reduction are happening before feeding to power generating units.
