Abstract

In this study, two different cycle systems on the base of Organic Rankine Cycle (ORC) have been designed for heat recovery from the industrial waste fluids at the low temperature to generate electricity using Engineering Equation Solver (EES).The designed cycles are Simple Organic Rankine Cycle (S-ORC) and Regenerative Organic Rankine Cycle (R-ORC). Waste fluid input temperature and mass flow rate are fixed in each cycle. Organic working fluids such as isopentane, isobutane, R134a, R123, R245fa, R22, R13, propane and R600 have been investigated. In order to detect the optimum working fluid, first (T1K) and second law of thermodynamics (T2K) values have been analyzed for each fluid. Finally, our study demonstrated that optimum fluids have been determined for different types of cycles and fluid pressure ranges.
