Oxidative dehydrogenation of propane (ODP) with CO₂ for propylene production is gaining increasing attention in recent years due to the advantages of CO₂ utilization, improved yield, and avoiding over oxidation problem. However, the process being highly endothermic, requires burning of fossil fuels to meet its heat demand leading to considerable CO₂ emission. Therefore, in the present study, a novel eco-friendly scheme for propylene production has been proposed for the first time that integrates ODP−CO₂ with chemical looping combustion (CLC) and it has the dual benefit of inherent CO₂ capture as well as its utilization. Further, the process is made self-sustained by recovering surplus heat and generating steam for power generation. Steady state plant wide simulation model of integrated CLC-ODP−CO₂ scheme is developed using ASPEN plus software. Rigorous sensitivity analysis has been performed to optimize the operating temperature, pressure and molar flowrates of oxygen carrier, CO₂ and propane resulting a maximum propylene yield of 79.1 %. Overall energy analysis of the integrated CLC-ODP−CO₂ scheme has resulted a net thermal efficiency of 73.48 %.

近年来，由于利用了CO ₂，提高了收率并避免了过度氧化的问题，用CO ₂进行丙烷的氧化脱氢（ODP）引起了丙烯的日益关注。然而，该过程是高度吸热的，需要燃烧化石燃料以满足其热需求，导致大量的CO ₂排放。因此，在本研究中，首次提出了一种新型的丙烯生产环保方案，该方案将ODP-CO ₂与化学回路燃烧（CLC）集成在一起，并具有固有CO ₂的双重优势。捕获及其利用。此外，通过回收多余的热量并产生用于发电的蒸汽，该过程可以自我维持。使用ASPEN plus软件开发了集成CLC-ODP-CO ₂方案的全厂稳态模型。进行了严格的灵敏度分析，以优化操作温度，压力和氧气载体，CO ₂和丙烷的摩尔流量，从而使最大丙烯收率达到79.1％。集成的CLC-ODP-CO ₂方案的整体能量分析得出净热效率为73.48％。
