Thermodynamic study of ORC at different working and peripheral conditions

Power generation from low temperature sources using Organic Rankine Cycle (ORC) was studied in this paper. A thermodynamic model was achieved in Aspen plus environment and the best working conditions were obtained for on-design conditions. Furthermore, off-design analysis is conducted for the cycle in this study. Results depict the effect of peripheral conditions on performance of the cycle. In addition, the effect of some possible working fluid defects on the performance of the cycle is considered at off-design conditions.
