A power supply complex is being created at the Kharasavey field of PJSC Gazprom to provide electricity to construction sites as part of the field arrangement. The operating company and the owner of the power supply complex is Allocation Hub LLC.

As the primary source of electric power, packaged gas-reciprocating power plants ROLT are used. GRPPs are made based on the engines of MWM TCG 2020 series (Caterpillar) with a unit capacity of 2.0 and 1.2 MW. The main consumer is a rotational camp for 5,000 people. The generating facility will also use mobile automated gas-turbine power plants PAES-2500 with a capacity of 2.5 MW each. These 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 ensured by the ENERGAS fuel gas treatment facility (FGTF). The maximum capacity of the facility is 8,000 m3 / h, including: consumption for GRPP – 5,000 m3 / h, for PAES turbines – 3,000 m3 / h.

FGTF is a multifunctional complex of two modules operating in cascade scheme. Fuel gas treatment module No. 1 (FGTM-1) is intended for preliminary separation, filtration and pressure reduction of the incoming gas. Then the fuel enters to FGTM-2, where the its final purification, flow measurement, heating and additional pressure reduction take place.

After successful completion of preliminary workshop tests, the FGTF has been shipped and is being transported to the site of power supply complex. The equipment is supplied in maximum factory readiness (98%) what further significantly reduces the duration of the construction and mounting works and pre-start activities.



Phased commissioning of the gas treatment facility will be implemented by the ServicENERGAS Company (part of ENERGAS Group). Technicians will perform erection supervision, start-up and adjustment works, own testing, comprehensive verification of FGTF in conjunction with gas-reciprocating power units, as well as training of operating staff.

REFERENCE:

The Kharasavey gas condensate field is located mainly on 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 2019, Gazprom began development of the Cenomanian-Aptian deposits here, the start of production is scheduled for 2023.
