Similar to a simple Rankine cycle, a basic organic Rankine cycle (ORC) consists of four processes: increasing pressure of the working fluid through a pump, high temperature heat addition through an evaporator, expansion of the high temperature as well as high pressure fluid through a turbine, and low temperature heat ...

The organic Rankine cycle is is similar to the Rankine steam cycle, but uses an organic fluid such as refrigerants and hydrocarbons instead of water as the working fluid. The ordinary Rankine cycle uses thermal power to convert water to steam, which expands through a turbine in order to generate electricity.

In contrast to a single loop ORC, a dual loop system has a high temperature loop for recovering the exhaust energy and low temperature loop for recovering the remaining energy of exhaust gas and the coolant energy andcan significantly reduce the exergy loss in the heat absorption process compared with conventional ...

The transcritical CO2-Rankine cycle is like the steam rankine cycle a condensation process. The CO2 passes through the two-phase region during the cooling process and is completely liquefied.
