Abstract:
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.

Claim (Index 21):
The ORC according to  claim 19 , wherein the control device will regulate the vapor fraction of the working fluid entering the expander, by switching repeatedly between two control algorithms, whereby the first control algorithm consists of varying the working fluid flow through the pump until the mechanical energy generated by the expander is at a local maximum and the second control algorithm consists of varying the working fluid flow through the expander until the mechanical energy generated by the expander is at a further optimized maximum.
