The PLP process uses low-to-high enthalpy geothermal fluid (T_hot,IN -> T_hot,OUT) to preheat and vaporize a suitable organic working fluid (Propane) within a closed loop:

▪ The organic fluid vapor rotates the turbine, which is coupled to the electric generator (E).

▪ The exhaust vapor flows through the condenser, which is cooled by air or water (T_cold,IN -> T_cold,OUT) .

▪ The organic working fluid is then pumped again, thus completing the closed-cycle operation.

In such way the ORC turbine is not in contact with the geothermal fluid, which remains enclosed in the heat exchangers, allowing a full reinjection of all the brine and steam condensate with zero emissions to the ambient.
