ENERGAS block-type gas treatment station has been put into operation at the power supply complex of the HAYAT plant

25 February 2022

This process unit provides commercial and process metering, filtration, pressure reduction and quality control of fuel for gas-consuming equipment of the power supply complex.

HAYAT Russia, a subdivision of Hayat Kimya Sanayi A.S., Turkey, is increasing its production capacities – a large plant for the production of sanitary and hygienic paper products is being built at the Borovsk site of the Kaluga special economic zone.

Here, an autonomous (decentralized) power supply complex is also being created to supply production with its own energy resources. Electricity will be generated by the two 10 MW gas turbine unit (GTU). The production of high-potential process steam will be provided by the two waste heat boilers with a productivity of 15 t / h each. In addition to the cogeneration power unit, the structure of the power supply complex includes an auxiliary gas boiler house.

The supply of the GTU and boiler house with fuel with the pre-set design parameters in terms of purity, temperature, pressure and flow rate will be guaranteed by the ENERGAS multifunctional system – a block-type gas treatment station (BGTS) and a booster compressor station (BCS).

BCS is intended to compress the fuel gas treated in the BGTS and feed it to the turbines with a pressure of 2.6 MPa and a temperature of +70°C. The maximum volume capacity of BCS is 6,336 m3 / h.

BGTS with a throughput of 9,317 m3 / h is intended for metering, filtration and pressure reduction of gas. Station is equipped with coalescing filters, the purification efficiency is 99.9% for solid particles larger than 3 microns and 100% for droplet moisture.

The purified gas is divided into two flows. The first one is directly headed to the BCS and then to the GTU turbines, the second one passes through a reduction system, which reduces the gas pressure and stabilizes it at the level required for feeding to the boilers (0.3 MPa).

At BGTS there is measured total volume of gas supplied to the power supply complex (commercial metering) and separately measured volume of fuel for the boiler house (process metering). Data are transmitted via communication channels to the upper level. Metering units with a relative error of no more than 1.5% made based on flow meters of ultrasonic type.

The gas treatment station is additionally equipped with fuel quality control assemblies located on the outlet pipelines and equipped with various measuring and analytical equipment.

BGTS is placed in a separate all-weather block-box with the integration of elements on a single frame, equipped with systems of working and emergency lighting, heating and ventilation, safety systems. The station is fully automated, the local control system is integrated into facility's APCS.

The BGTS is put into operation – at this stage (before the gas turbines launch), the process unit provides fuel to the boiler house of the power supply complex. The compressor station is being prepared for workshop testing and delivery to the facility.

Commissioning of the whole gas treatment and fuel supply system – erection supervision, starting-up and adjustment, own and integrated tests as well as training of operational personnel are carried out by the specialists of ServicENERGAS (ENERGAS Group).


Among the priorities of the ENERGAS Group are production, comprehensive commissioning and maintenance of gas treatment and compression units for generating facilities in the electric power industry, oil and gas complex and industrial enterprises. Today, the ENERGAS process equipment provides high-quality fuel for 220 gas turbines and gas-reciprocating units with a total capacity of over 6.7 GW.
