FIELD: heating.
SUBSTANCE: invention refers to gas engineering, particularly to gas distribution stations for gas pressure reduction in gas pipeline. Gas distribution station includes control unit, process unit with high and low pressure gas pipelines, condensate accumulation vessel connected to HP gas pipeline and via shutoff unit to LP gas pipeline, ejector, vortex tube mounted in HP gas pipeline, heat exchanger connected to hot flow outlet of vortex tube, cold flow outlet of which is connected to condensate drain. Control unit features ambient temperature sensor and flow rate controller for hot flow of vortex tube, positioned at ejector inlet. Plate heat exchanger is located in recirculation loop of heating system, its outlet is connected to ejector inlet. Ejector outlet is connected to LP gas pipeline, ejector mixing chamber is connected to condensate drain. External surface of condensate accumulation vessel is coated with heat insulating and heat accumulating material in the form of extended thin basalt fibre bundles oriented vertically.
EFFECT: maintenance of set heat and mass exchange process for moisture removal to condensate accumulation vessel.
