What are the working fluids in the organic Rankine 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 working fluid in the Rankine cycle?
Unlike the commonly used Rankine Cycles, which operate on the water as the working fluid (so-called as the steam power cycles), the ORCs operate on organic fluids.

How does the organic Rankine cycle work?
ORC: How it works
In a typical ORC design, a thermal energy source feeds an evaporator to drive an expander or “reverse compressor”, which in turn generates the electricity. The provider of the heat can be natural, such as in the case of geothermal energy, or waste heat from any number of industrial waste heat sources.
