FIELD: oil and gas production.
SUBSTANCE: procedure consists in implementation of compressor module containing case of high pressure with electric engine installed in it and via drive connected to compressor by means of shaft. The shaft is installed in magnetic bearings. Axial packing is arranged around the shaft and it divides the case of high pressure into the first compartment with the electric engine and the second compartment equipped with an inlet orifice and outlet orifice for compressed fluid medium. According to the invention in a storage there is set excessive pressure with consideration of required flow rate of protective gas through axial packing and pressure in the second compartment. Also, supply of protective gas is controlled in at least the first department by means of a control device installed in a supplying line.
EFFECT: raised efficiency of procedure.
