Neva-25NK gas compression package at Gryazovets compressor station (Severgazprom) successfully passed 72-hour tests

The tests confirmed the declared parameters of Neva-25NK gas compression package (Moto-rostroitel, Samara).

The design feature of the project is that the compression package equipment was assembled in the already existing building. The power package is supplied with NK-36ST gas turbine with the nominal output of 25 MW and the efficiency of 36% (ISO). NK-36ST gas turbines have been in serial production since 1996. The compression ratio of NK-36STgas turbine is 23.1, the exhaust gas flow is 101.3 kg/sec, the power shaft rotation speed is 5000 rpm, the inlet air temperature is 1454 K, the exhaust gas temperature is 730 К, the NОx emission is 75 ppm.
The 598-21-1SU natural-gas compressor is manufactured by Compressor Complex (St. Pe-tersburg).
