Zusammenfassung: | FIELD: development of compressor plants designed for production of nitrogen-air mixture from atmospheric air in the field conditions in production operations in oil production and gas branches of industry. ^ SUBSTANCE: the method consists in the fact that atmospheric air is prepared to partial separation of oxygen, passed through a gas separation plant and compressed to the operating pressure. Preparation of gas mixture to gas separation is performed in parallel by two small-sized multi-step compressors. Partial separation of oxygen is performed after the third step with employment of the hollow fiber process. Final compression of the nitrogen-air mixture to the operating pressure is performed in the fourth step of the compressors. The device has two small-sized compressors providing for a parallel acting multistep process of preparation of air mixture to gas distribution, and a commutator. The drive of one compressor through a mechanical coupling and a cardan shaft is effected from a diesel engine truck, and that of the second compressor - from the truck chassis. ^ EFFECT: considerably reduced mass and overalldimensions of the plant, enhanced its mobility. ^ 2 cl, 1 dwg |
