Abstract
A system for depressurizing a gas in a pipeline is described. The system com-prises an expander configured and arranged for generating mechanical power by expanding gas from a first pressure to a second pressure. The system further comprises a heat pump and a heat transfer circuit containing a heat transfer fluid circu-lating therein, for receiving heat from the heat pump and delivering heat to the gas through a heat exchanger. A controller is further provided, configured and arranged for modulating a flow rate of the heat transfer fluid circulating in the heat transfer circuit as a function of a heat rate to be transferred from the heat transfer fluid to the gas, particularly as a function of temperature differentials between the gas and the heat transfer fluid at a gas inlet side and a gas outlet side of the heat exchang-er.
