FIELD: gas industry.
SUBSTANCE: method includes separating gas with a vortex pipe into cold and hot gas flows, heating the cold flow in the heat exchanger, and combining two flows. Before separation, gas is throttled and heated using the heat from heat exchanging section of the gas pipeline. The hot flow from the vortex pipe and preliminary heated flows are mixed. The pressure of mixed gas flow is controlled automatically depending on temperature, pressure, required gas flow rate, and temperature in the pipeline to provide maximum temperature of the gas.
EFFECT: enhanced efficiency.
