“…But if the cycle uses organic matter as a working fluid, it is called the organic Rankine cycle and works at low energy sources of solar heat or waste heat [4][5][6][7][8][9][10][11][12]. This cycle is simple in construction, easy to maintain, and highly reliable [13][14][15][16][17][18][19][20][21]. Delgado and Garcia [22], carried out a theoretical analysis of ORC coupled to solar collectors for desalination applications.…”

This paper investigates finding the best working fluid to improve the giving of the solar organic Rankine cycle. A parabolic trough solar complex was designed to focus the sun rays on a vicious cylinder to produce sufficient steam to operate the ORC. The steam is collected in an isolated tank filled with molten salt called an evaporator. The heat gained in this evaporator is transferred to feed the power generation turbine. Ten different working fluids of R123, R143a, R433A, R290, R40, R22, R600a, R601, RC318 and R1270 were tested at a boiling temperature from 150°C to 240°C. The results showed that using R601 as a working fluid for ORC gave the highest thermal efficiency compared to other organic liquids tested at temperatures from 150 to 240 °C. R601 gives a gain in cycle thermal efficiency by about 24.6% relative using R600a. While R 290 gave an improvement in the power produced by the turbine estimated at 10% higher than that used at higher temperatures above 240° C.

“…In another study, Braimakis et al [ 31 ] optimized three improved designs of regenerative ORC using various working fluids from an energy analysis perspective. The coupling of a vapor compression cycle with an ORC for heat recovery purposes has been investigated by Zhar et al [ 32 ]; through a multi-objective optimization of their parametric analysis, the proposed system’s return of investment was calculated to be 6.3 years. The implementation of ORC to recover the waste heat capacity in the aluminum industry has been studied by Dokl et al [ 33 ].…”

In recent decades, there has been an increasing trend toward the technical development of efficient energy system assessment tools owing to the growing energy demand and subsequent greenhouse gas emissions. Accordingly, in this paper, a comprehensive emergy-based exergoeconomic (emergoeconomic) method has been developed to study the biomass combustion waste heat recovery organic Rankine cycle (BCWHR-ORC), taking into account thermodynamics, economics, and sustainability aspects. To this end, the system was formulated in Engineering Equation Solver (EES) software, and then the exergy, exergoeconomic, and emergoeconomic analyses were conducted accordingly. The exergy analysis results revealed that the evaporator unit with 55.05 kilowatts and the turbine with 89.57% had the highest exergy destruction rate and exergy efficiency, respectively. Based on the exergoeconomic analysis, the cost per exergy unit , and the cost rate of the output power of the system were calculated to be 24.13 USD/GJ and 14.19 USD/h, respectively. Next, by applying the emergoeconomic approach, the monetary emergy content of the system components and the flows were calculated to evaluate the system’s sustainability. Accordingly, the turbine was found to have the highest monetary emergy rate of capital investment, equal to , and an output power monetary emergy of . Finally, a sensitivity analysis was performed to investigate the system’s overall performance characteristics from an exergoeconomic perspective, regarding the changes in the transformation coefficients (specific monetary emergy).

“…They highlighted that heptane and cyclohexane are the most convenient refrigerants. Zhar et al [16] observed that R123 presents the highest ORC energy and exergy efficiency with 6.3 years payback period. [17] concluded that butane results in the highest power generation than other working fluids (R600a, R601a, R245fa, R245ca, R236ea), and waste heat recovery increases the energy and exergy efficiency by 37.7% and 35.7%, respectively.…”
