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.
