Organic Rankine Cycle technology for flexible combined-cycle power plants in the MENA regions

In today’s MENA regions, ICEs and GTs though tend not to be optimised for combined-cycle operation, and their exhaust gas temperatures are not sufficiently high, especially under part-load conditions, to generate steam at the conditions needed to achieve a high overall electrical efficiency. Thanks to its impressive development in high-enthalpy applications, Organic Rankine Cycle (ORC) technology, using specific organic working fluids, permits the efficient exploitation of low-temperature exhaust gas streams, also at variable load and/or on poor quality fuels.
