GAS-DISTRIBUTING STATION Russian patent published in 2011 - IPC F17D1/04 

FIELD: machine building.

SUBSTANCE: gas-distributing station consists of control unit, of process unit with gas line of high and low pressure, of accumulating condensate reservoir connected with high pressure gas line and via gate with gas line of low pressure, of ejector, of heat exchanger, of vortex pipe installed on gas line of high pressure, while outlet of its cold flow is connected with condensate extractor. The heat exchanger is made in form of a closed reservoir with liquid of a gas distributing station heating system with circulation pipeline. The vortex pipe is positioned in the heat exchanger and is immersed into liquid. An inlet of the ejector is connected with an outlet of a hot flow of the vortex pipe through a ribbed pipe located in a lower section of the heat exchanger. The outlet of the ejector is connected with the pipeline of low pressure and its mixing chamber is connected with the condensate extractor.

EFFECT: elimination of non-manufacture consumption of natural gas at its combustion in system of gas distributing station premises at negative temperature of environment; increased reliability of operation by utilisation of gas pressure drop between gas pipes of high and low pressure as source of heat radiated in vortex pipe in heat exchanger.
