Waste heat recovery from industrial processes has attracted much attention in the energy field in the past few decades. This paper introduces a new configuration of the triple cycle including gas and steam cycles as well as an organic Rankine cycle (ORC), for energy recovery from the hot exhaust gas. Also, the amine carbon capture system (CCS) is used to separate and store carbon dioxide from the hot exhaust gas. For this novel system, energy, exergy, economic, exergoeconomic, and exergoenvironmental (5E) assessments are accomplished. The results reveal that adding steam and ORC cycles to the gas cycle increases the energy and exergy efficiencies to 71.8 and 73.7, respectively. However, integration of the CCS unit to this system reduces energy and exergy efficiencies to 50.5 % and 51.9 %. The economic results for the proposed system show that SPP and PP are both 1.5 years. Moreover, NPV and IRR are found to be 3.13 × 09 $ and 0.68 respectively. Moreover, the carbon capture system (CCS) unit can avoid 627,000 metric tons of CO2 emissions annually.

含碳捕集三重循环的能源,火用,经济,能效经济和能效环境(5E)分析

在过去的几十年中,从工业过程中回收余热在能源领域引起了广泛关注。本文介绍了一种三重循环的新配置,包括气体和蒸汽循环以及有机朗肯循环(ORC),用于从热废气中回收能量。而且,胺碳捕获系统(CCS)用于从热废气中分离和存储二氧化碳。对于这个新颖的系统,完成了能源,火用,经济,能效经济和能效环境(5E)评估。结果表明,在气体循环中增加蒸汽和ORC循环可将能量效率和火用效率分别提高到71.8和73.7。但是,将CCS单元集成到该系统后,能量和火用效率分别降低到50.5%和51.9%。拟议系统的经济结果表明,SPP和PP均为1.5年。此外,NPV和IRR为3.13×09 $和0.68。此外,碳捕集系统(CCS)单元每年可减少627,000公吨的CO 2排放。
