Gas distribution station with power plant

A gas distribution station comprising:

• a gas main containing a pressure reducer,
• a power plant,
• a heat exchanger having an inlet connected to said gas main upstream of said pressure reducer for flow of gas from the gas main through the heat exchanger,
• said power plant including a gas turbine engine having a second heat exchanger through which combusted gases from the gas turbine engine pass,
• said first heat exchanger being connected to said second heat exchanger so that gas from the first heat exchanger flows to the second heat exchanger, whereat said gas is heated by the combusted gasses passing through the second heat exchanger,
• a turbo-expander connected to the second heat exchanger for receiving the heated gas therefrom which drives said turbo-expander and undergoes cooling therein, said turbo-expander having a gas outlet at which the gas is discharged in an expanded and still heated state,
• an electric generator connected to said turbo-expander for being driven thereby,
• said gas outlet of said turbo-expander being connected to said first heat exchanger for passage through the first heat exchanger of the heated gas from the turbo-expander, said heated gas from the turbo-expander undergoing heat exchanger with the gas passing through the first heat exchanger coming from the gas main to heat said gas coming from the gas main,
• said first heat exchanger being connected to said gas main at a locating downstream of said pressure reducer to supply to said gas main the heated gas from the first heat exchanger after said heated gas has undergone heat exchange in said first heat exchanger.
