Organic Rankine cycle (ORC)

As precise temperature control, excellent thermal stability, and heat transfer coefficients are key for reliable operation, Eastman Therminol® heat transfer fluids are widely used for Organic Rankine cycle (ORC) system applications. ORC systems are widely used in the production of electricity from biomass combustion or safe recovery of thermal energy from exhaust gases from industrial processes such as cement, glass, or metal processing plants. This expanding “green” technology is helping to reduce the global energy footprint. ORC is a process designed to use high- or medium-temperature Therminol fluids with lower operating pressures and higher partial load efficiency than steam-driven conventional power plant turbines. ORC hybrid applications, such as combined concentrated solar power (CSP) and ORC, are also finding Therminol products to be excellent heat transfer media.
