The experts of the service company belonging to the ENERGAS Group carried out a technical audit of the booster compressor station operating as part of the complex for testing gas turbine units (GTU) of Proton-Perm Motors PJSC. This BCS feeds the testable turbines with gas that meets the specified parameters in terms of purity, temperature, pressure and flow rate.

As a result of the inspection there were compiled defect sheets, prepared recommendations on replacement of defective and exhausted assemblies and components, proposed plan for local restoration works and major repair of the station.



BCS for fuel gas was installed here in December 2011. Equipment was specially devised to operate in conditions of various tests duration and high intensity of starts.

The project requirements for the gas purity are ensured by the multistage filtration system of BCS: inlet protective strainer, gas-oil separator of the 1st stage of purification and coalescing (safety) filter of the 2nd stage. Thus, compliance of the fuel with the set norms is guaranteed: the content of mechanical impurities in gas at the outlet is no more than 2 ppmw (mg / kg), the degree of purification from solid particles larger than 10 microns and liquid fraction is 100%.

Highly efficient compressor module gives a high gas compression ratio: the pressure at the suction is 0.5 MPa, the pressure at the delivery line can be provided in the range of 1.6 ... 4.5 MPa – depending on the type and settings of conjugated GTU and the testing algorithm.

The process flow scheme provides for the stable maintenance of the calculated fuel temperature. The delivery line of the BCS is equipped with a shell-and-tube heat exchanger that cools the working medium and guarantees the optimum gas supply temperature set by the turbo unit manufacturer.

The volume productivity of compressor station varies from 2,500 to 11,000 m3 per hour. The actual gas flow rate depends on the capacity and dynamics of the load of associated turbine, and is controlled in the range from 0 to 100% of nominal. For this purpose, a special two-tier productivity regulation system is used, which allows the BCS to respond as quickly and correctly as possible to changes in the operating mode of the testable GTU and fluctuations in the parameters of the inlet pipeline, as well as, if necessary, to operate the station in the gas recirculation mode.



Packaged BCS is fully automated and is housed in its own all-weather shelter, equipped with life support systems (heating, ventilation, and lighting). According to safety requirements, process unit is equipped with fire detection, gas detection, alarm and fire fighting systems.
