Abstract: In recent years, waste heat recovery (WHR) systems based on Rankine cycles have been the focus of intensive research for transport applications, as they seem to offer considerable potential for fuel consumption reduction. Because of the highly transient conditions they are subject to, control plays a fundamental role to enable viability and efficiency of those systems.
a waste heat recovery system in such vehicles can offer energy recovery benefits in various forms that can further increase the efficiency of the powertrain by approximately 10 15% and also reduce harmful emissions [4,9,14,25]. 4. Organic Rankine Cycle (ORC)
A Rankine cycle using organic fluids as working fluids, called organic Rankine cycle (ORC), is potentially feasible in recovering low enthalpy containing heat sources. Efficient operation of the ORC depends heavily on two factors: working conditions of the cycle and the thermodynamic properties of the working fluids.
Geothermal and Waste heat (ORC) power generation Generating renewable electricity from geothermal resources and waste heat requires the best use of available technologies.

Pulp and paper mills usually feature medium grade heat in the recovery boiler stack of black liquor due to limited boiler efficiency and safety reasons. The unused heat is to be recovered and used to generate power using an Organic Rankine Cycle (ORC). The waste heat from the ORC is also recovered and used for water heating.
If you have the accessible source of waste heat and a use for the recovered energy, all you then need is the recovery technology. Much of the industrial waste heat is in the low-temperature range (100-400°F). One technology available for this type of waste heat recovery is organic rankine cycle (ORC) technology.

Waste heat recovery is one of the most important development fields for the organic Rankine cycle (ORC), where a low boiling point organic fluid is used as a working medium. The ORC can be applied to heat and power plants or to industrial and farming processes. Some heat sources, like hot exhausts from furnaces, which contain particles or sulfide might harm pipes of an evaporator.

The organic Rankine cycle (ORC) system is a very strong candidate for converting low-grade waste heat into power. However, there is a lot of water vapor containing latent heat in the exhaust gases from the drying process in the paper industry.
With the use of an adapted Organic Rankine Cycle (ORC), waste heat sources at low-temperature, can be recovered. An ORC uses a closed circuit with an organic working fluid which can be evaporated and condensed at low temperatures and pressures. The fluid is evaporated and is forced to pass through an expander to generate electricity.
An Organic Rankine Cycle (ORC) unit is a power generation system which uses heat as its energy input and converts this heat to electricity. The system is similar to a conventional Rankine Cycle (i.e. a steam turbine based system), with the key difference being that the steam is replaced with an organic working fluid.
