The working principle of the organic Rankine cycle is the same as that of the Rankine cycle: the working fluid is pumped to a boiler where it is evaporated, passed through an expansion device (turbine, screw, scroll, or other expander), and then through a condenser heat exchanger where it is finally re-condensed.

The organic Rankine cycle (ORC), which is a closed energy harvesting power cycle that uses an organic fluid with a low boiling point [21], has been widely investigated as a promising energy harvesting technique for recovering thermal energy from low-grade thermal sources such as geothermal sources [22], solar energy, ...

The Organic Rankine Cycle's principle is based on a turbogenerator working as a conventional steam turbine to transform thermal energy into mechanical energy and finally into electric energy through an electrical generator.

In our case study, the expected generated electric power is 1,750 kW or equivalently, 15,000,000 kWh of electrical energy annually. Financial analysis shows that the ORC system, including the cost of the unit plus the costs of installation and integration into the process, will cost approximately 4.8 Million USD.
