This study proposes an innovative system for recovering waste heat from exhaust air after a regenerative thermal oxidiser process, integrating Carnot battery and photovoltaic (PV) modules. The incorporates organic Rankine cycle (ORC) with recuperator, energy storage (TES), pump. Waste is initially captured in TES, additional extracted by pump to increase the temperature of secondary fluid, effectively charging TES both direct indirect sources. stored enables electricity generation via ORC. result this shows COP between 2.55 2.87, efficiency ORC ranging 0.125 0.155, power-to-power 0.36 0.40. Moreover, PV generates 1.35 GWh annually, primarily powering proposed total annual net 4.30 GWh. Economic evaluation across four configurations demonstrates favourable outcomes, return on investment 25% 160%. economic examined without recuperation process Results indicate that incorporating recuperator significantly increases power output, offering highly viable sustainable solution.

Polygeneration systems have significant potential for energy conservation and emission reduction can effectively promote green low-carbon development in energy-intensive industries, such as the iron steel industry. However, its application faces difficulty technology selection under multiple objectives simultaneously, which is to determine portfolio achieve synergy of goals air pollutant goals, well ensure economic benefits enterprises. This study investigated a case polygeneration system where plant are core with four paths twenty technologies. A multi-objective optimization model developed select optimal combination each path conservation, reduction, cost control objectives, solved by non-dominated sorting genetic algorithm-II (NSGA-II). The results reach effects while obtaining benefits. synergistic conflicting relationships among exist both scales plants. final decision scheme mitigations equivalent 15.9–27.1% 16.3–42.6% consumption emissions enterprises annual production 3 Mt/a 9 Mt/a, respectively. There thirteen twelve technologies that selected these two These findings demonstrate roles plays provide critical insights methodology technical system.
