Low-temperature waste heat can be recovered from the gas turbine exhaust, typically using organic Rankine cycle technology, and used to generate electricity.

What are the steps in the organic Rankine cycle?
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.
What is the ORC organic Rankine cycle?
An Organic Rankine Cycle (ORC) system is a closed thermodynamic cycle used for power production from low to medium-high temperature heat sources ranging from 80 to 400°C and for small-medium applications at any temperature level.
What are the working fluids in the ORC cycle?
This study considered five different working fluids for ORC, such as R245fa, Benzene, Methanol, Ethanol, and Acetone. The ORC generates additional electricity of 9.91 MW e for R245fa, 14.11 MW e for Benzene, 13.71 MW e for Methanol, 14.04 MW e for Ethanol and 13.97 MW e for Acetone.
What is the difference between Rankine cycle and ORC?
An organic Rankine cycle (ORC), is fundamentally the same as a steam Rankine cycle; however, it uses a lower boiling point organic fluid to better match its operation to lower temperature heat sources. ORC systems can achieve better efficiencies than steam turbines for smaller systems (less than a few MWe).
