Performance assessment of different Organic Rankine Cycle (ORC) configurations driven by solar energy

Summaiya Javed et al.

Summary: This paper compares three Organic Rankine Cycle (ORC) configurations - Basic, Recuperative and Regenerative - from both an energy and economic perspective. Four different organic working fluids (Toluene, Nonane, Decane and Dodecane) are used in the simulation of the three configurations using Aspen Plus software. Energy analysis is conducted to evaluate the net work done, power, and efficiency of the ORC systems. The study shows that the Regenerative ORC configuration with Toluene as the working fluid demonstrates the highest net work done and efficiency. Thermo-economic analysis also reveals that the Regenerative configuration has the lowest operating cost.

Thermodynamic optimization and comparative economic analysis of four organic Rankine cycle configurations with a zeotropic mixture

Arvin Sohrabi et al.

Summary: This study compares four fundamental Organic Rankine Cycle structures using a zeotropic mixture of Pentane and Hexane as the working fluid, finding that the recuperative dual-pressure ORC is the most efficient with the highest power generation, but economically less acceptable. The levelized cost of electricity for each mole fraction was calculated to conduct thermoeconomic analysis, revealing the superiority of recuperative structures in terms of net present value.

Optimal design and operation of an Organic Rankine Cycle (ORC) system driven by solar energy with sensible thermal energy storage

Haoshui Yu et al.

Summary: In this study, the optimal design and operation of an Organic Rankine Cycle (ORC) system driven by solar energy were investigated. A simulation-based optimization model was developed to maximize system efficiency, with findings showing that supercritical ORC outperforms subcritical ORC. Toluene was identified as the best working fluid, while the system efficiency was significantly improved compared to previous studies.

A novel working fluid selection and waste heat recovery by an exergoeconomic approach for a geothermally sourced ORC system

Zekeriya Ozcan et al.

Summary: A novel methodology for working fluid selection in organic Rankine cycles coupled with low-grade geothermal sources is proposed, which successfully selects a new working fluid for geothermal power plants based on thermodynamic and thermoeconomic evaluations. The results show improvements in plant efficiencies and reduced electricity costs compared to the base plant outputs, demonstrating the potential benefits of the proposed methodology.
