NITROGEN COMPRESSOR STATION Russian patent published in 2015 - IPC F04B41/00 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to compressor equipment, mainly to mobile compressor stations with membrane nitrogen generators, for obtaining of a neutral nitrogen-based gas mix. The station has a screw compressor 1, membrane gas separation unit 3, oil separator 4, air conditioning unit 5 and oil circulation system. The gas separation unit 3 contains the main section 6 and additional sections 7 and 8. The oil circulation system of the compressor 1 includes the oil separator 4, an oil channel of an air heater 18, an oil cooling heat exchanger 24 with a fan 25. The oil cooling heat exchanger 24 and the gas separation unit 3 are located so that the heated air flow downstream the oil cooler flows around the housing details of membrane modules, and towards the movement of the heated air of the section of the gas separation unit are located in a sequence 7-8-6.

EFFECT: heating of switched-off modules is provided and, besides, at the established operating mode of the station the optimum thermal mode of the gas separation unit is ensured.
