The booster compressor station of fuel gas for the GTU-TPP under construction in Elabuga passed preliminary (factory) tests

26 August 2017

In the city of Elabuga (the Republic of Tatarstan) a new GTU-TPP is being built at the site of the Central boiler house. The generating equipment consists of four gas turbine units Solar of type Taurus 60 GS with a unit capacity of 5.6 MW and four hot-water waste-heat boilers. The installed electrical capacity of the station will be 22-23 MW.

For GTU-TPP, ENERGAS will supply a comprehensive gas treatment system - a gas treatment unit (packaged gas purification unit - PGPU) and a booster compressor station. This process equipment will be put into operation by ENERGAS step by step.

The main elements of the PGPU are a gas purification system consisting of three filtration lines and a drainage module, and a two-line gas metering unit. Additional equipment is a continuous chromatograph (calorimeter) and a dew point measurer with sampling devices. 

After preliminary treatment, the gas flow is directed to the booster compressor station, including two screw-type units. The BCS compresses and feeds fuel gas to the turbines at the required design pressure of 1.65 MPa. The process scheme of the BCS also provides for the provision of a set gas feeding temperature to the GTU-TPP. 

The capacity of the comprehensive gas treatment system is 8,240 m3 / h. All units are automated; local ACS will be integrated into the APCS of the thermal power plant. Equipment version - container, block-modules are equipped with safety and life support systems. 

Currently there is completed preliminary (factory) testing of gas compressor station, during which the functioning of the all main elements - process, compressor, measuring, electrical equipment - was checked. Also, the ACS, oil system, valves actuation, integrity of cable lines, tightness and leak-tightness of BSC have been tested.
