Abstract:
1. A method for recovering energy in a gas compression plant during recirculation mode, the method comprising: providing for at least one turbo-expander and at least one valve connected in parallel in the portion of the plant arranged downstream of at least one compressor, and an electric current generator coupled exclusively to the turbo-expander, wherein the electric current generator is configured to recover energy from a recirculation system connected to the at least one compressor; measuring a flow rate of gas and a working condition of said at least one compressor by means of at least one sensor arranged on a suction side of the compressor and at least one sensor arranged on a delivery conduit of the compressor; and actuating, by means of an electronic device, said valve and said turbo-expander according to the flow rate of gas and the working conditions measured by the sensors.
