Gas expansion device for expanding a gas or a gas-liquid mixture, where the gas expansion device includes a gas expansion element with an inlet port for the gas to be expanded and an inlet pipe for the gas to be expanded. The inlet pipe is connected to the inlet port where the gas expansion device includes a first liquid injection point for the injection of liquid, where the first liquid injection point is at a position level with the inlet port or upstream from the inlet port.

Gas expansion device and method for expanding gas

An Organic Rankine Cycle (ORC) device and method for transforming waste heat from a heat source containing compressed gas into mechanical energy. The ORC includes a closed circuit containing a two-phase working fluid, the circuit including a liquid pump for circulating the working fluid in the circuit consecutively through an evaporator which is in thermal contact with the heat source; through an expander like a turbine for transforming the thermal energy of the working fluid into mechanical energy; and through a condenser which is in thermal contact with a cooling element. The ORC determines the mechanical energy generated by the expander. A control device regulates the fraction of the working fluid entering the expander based on the determined mechanical energy such that the mechanical energy generated by the expander is maximum.

An Organic Rankine Cycle (ORC) device and method for transforming heat from a heat source into mechanical energy. The ORC includes a closed circuit containing a two phase working fluid. The circuit comprises a liquid pump for circulating the working fluid consecutively through an evaporator which is configured to be placed in thermal contact with the heat source; through an expander for transforming the thermal energy of the working fluid into mechanical energy; and through a condenser which is in thermal contact with a cooling element. The expander is situated above the evaporator. The fluid outlet of the evaporator is connected to the fluid inlet of the expander by a raiser column which is filled with a mixture of liquid working fluid and of gaseous bubbles of the working fluid, which mixture is supplied to the expander.
