“…The environmental and sustainability impacts of the proposed processes would be estimated by indirect CO 2 , SO 2 and NO X emissions. In this study, the gas emissions are calculated as follows: 34

G_{e} = A \cdot M_{coal} + B \cdot Q_{comp}

M_{coal} = \frac{Q_{con} \cdot T}{Q_{standard}}

BACKGROUND Biobutanol is considered to be a promising alternative biofuel in terms of sustainability and environmental friendliness because of its desirable properties. High purity isopropanol–butanol–ethanol (IBE) mixture can be directly used as gasoline additive. However, the purification process of IBE is hindered because of its low concentration and high energy consumption. In order to reduce energy consumption and improve the efficiency of the IBE purification process, two novel processes combining liquid–liquid extraction with extractive distillation or azeotropic distillation are proposed. Moreover, the heat integration designs of the processes are carried out to further reduce energy. These processes are compared with regard to energy, economic, environmental and exergy impact. RESULTS The results show that the energy consumption of these enhanced processes are effectively reduced compared with the original process in the literature. Among them, the thermal integrated process of liquid–liquid extraction combined with extractive distillation is the best design, which has a total annual cost of $32.656 × 105 and an energy consumption of 5936.94 kW. CONCLUSION Compared with the original process, this process can save 71.33% of energy consumption. © 2021 Society of Chemical Industry

“…However, it does not provide information related to the potential ability of a system to deliver work (Souza et al, 2020). The irreversibility must be accounted for during the evaluation of the system ability (Liu et al, 2020). Therefore, the exergy destruction in different components of the system must be evaluated.…”

The organic Rankine cycle (ORC) has recently emerged as a practical approach for generating electricity from low-to-high-temperature waste industrial streams. Several ORC-based waste heat utilization plants are already operational; however, improving plant cost-effectiveness and competitiveness is challenging. The use of thermally efficient and cost-competitive working fluids (WFs) improves the overall efficiency and economics of ORC systems. This study evaluates ORC systems, facilitated by biogas combustion flue gases, using n-butanol, i-butanol, and methylcyclohexane, as WFs technically and economically, from a process system engineering perspective. Furthermore, the performance of the aforementioned WFs is compared with that of toluene, a well-known WF, and it is concluded that i-butanol and n-butanol are the most competitive alternatives in terms of work output, exergy efficiency, thermal efficiency, total annual cost, and annual profit. Moreover, the i-butanol and n-butanol-based ORC systems yielded 24.4 and 23.4% more power, respectively, than the toluene-based ORC system; in addition, they exhibited competitive thermal (18.4 and 18.3%, respectively) and exergy efficiencies (38 and 37.7%, respectively). Moreover, economically, i-butanol and n-butanol showed the potential of generating 48.7 and 46% more profit than that of toluene. Therefore, this study concludes that i-butanol and n-butanol are promising WFs for high-temperature ORC systems, and their technical and economic performance compares with that of toluene. The findings of this study will lead to energy efficient ORC systems for generating power.

“…Also, they utilized the algorithm genetic method to optimize the cost and exergy destruction of their system. Liu et al 17 performed 4E analyses of a combined generation system including CO 2 capture system, organic Rankine cycle, and absorption refrigeration system. The ORC efficiency and exergy destructions of the ORC and absorption system were evaluated, and the life cycle assessment was utilized for environmental analysis of the system.…”
