INSTALLATION FOR COMBINED ELECTRICAL AND COLD SUPPLY AT GAS DISTRIBUTION STATION Russian patent published in 2018 - IPC F17D1/04 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of heat power engineering, specifically to the use of natural gas in energy and cold production facilities through the use of a differential pressure of natural gas at gas distribution stations (GDS). Unit for combined electric and cold supply on the gas distribution system is mounted between a high-pressure gas pipeline and a low-pressure gas pipeline and contains the main natural gas supply line to an expander that is kinematically connected to an electric generator, a dehumidifier installed in front of the expander, and a heat exchanger whose input is connected to the expander output. Unit comprises a main gas heater connected in the high-pressure gas line before the drying unit and an additional natural gas supply line, which passes from the second outlet of the main gas heater through the pressure regulator and is connected to the main natural gas supply line in the low pressure gas pipeline, and an additional gas heater with a regulator is connected to the outlet of the heat exchanger to control the temperature of the gas sent to the low-pressure gas pipeline, and the heat exchanger is connected by pipelines of supply and discharge of the coolant to the consumer of the cold.

EFFECT: purpose of the invention is to increase the economic efficiency of utilizing the potential energy of natural gas on the GDS, simplifying the design of the installation for such utilization.
