ENERGAS end system of filtration is intended to ultrafine purification of gas fuel at the inlet to the shut-off valve block of SGT-800 turbines.

At the Novopolotsk CHPP, the 100 MW gas turbine power plant (GTPP) based on two Siemens SGT-800 turbines is being created. It is one of four peak-standby energy source (PSES) which will be constructed for the unified power grid of the Republic of Belarus.

Being in the mode of continued readiness to launch, the new facility will maintain, if necessary, the balance of generation and consumption of electricity. The equipment of the GTPP is characterized by high maneuverability – it will take less than 15 minutes to responsively start it and fill the power deficit in the power grid.

Under a contract with Siemens Energy, the Russian Company ENERGAS will supply gas treatment and fuel supply equipment to Novopolotsk PSES – a gas receiving station and an end system of filtration. This equipment will ensure the design parameters of the fuel before its feeding into turbines.

The ENERGAS gas receiving station is a process unit, the main purpose of which is flow measuring and preliminary filtration of gas. The capacity of the station is 29,210 m3 / h – similar to the rated fuel consumption of GTPP.



ENERGAS end system of filtration is intended to ultrafine purification of gas fuel at the inlet to the shut-off valve block of SGT-800 turbines. SF consists of four filters of vertical cartridge type with a throughput of 14,890 Nm3 / h each.

Filtration efficiency is 99.9% for particles larger than 0.01 microns. As a result, the residual content of impurities in purified gas does not exceed 0.001 ppmw (mg / kg). Coalescing filters are being equipped with pressure differential sensors that signal the contamination of replaceable elements. The signals will go directly to the upper level of the APCS.



REFERENCE:

Novopolotsk CHPP is the branch of RUE Vitebskenergo. Its installed capacity is 270 MW. Annual electricity output amounts to 0.8-0.9 billion kWh, and issue of heat ranges from 2.8 to 3 million Gcal.
