| description | This study explores enhancements in CO<sub>2</sub> capture and release using monoethanolamine (MEA) combined with iron oxide nanoarticles (IONPs) in a 10 kg per day pilot CO<sub>2</sub> capture plant. Previous studies highlighted the potential of nanoparticle additives to improve CO<sub>2</sub> capture via modeling and batch experiments; however, robust experimental evidence at the pilot scale is necessary for commercialization. This pilot plant employed a thermal swing process using synthetic CO<sub>2</sub>–flue gas mixtures, conditioning systems, and Programmable Logic Controller (PLC)-based controls for heating, operation, and data acquisition. IONPs, synthesized through chemical precipitation and characterized by XRD and HR-SEM, were integrated into MEA at concentrations of 0.0001% <i>w</i>/<i>v</i> (1 ppm), 0.001% <i>w</i>/<i>v</i> (10 ppm), and 0.002% <i>w</i>/<i>v</i> (20 ppm). Their electromagnetic properties enhanced mass transfer during absorption and significantly reduced heat demand during stripper desorption. Higher concentrations of IONPs decreased desorption temperatures by up to 7 °C, resulting in estimated energy savings of approximately 10–15%, while achieving CO<sub>2</sub> loading rates up to 0.34 mol CO<sub>2</sub>/mol MEA. Structural stability of the IONPs was confirmed via XRD and HR-SEM analyses following extended thermal cycling. Utilizing a common solvent and abundant catalyst, these demonstrated improvements underscore the practical scalability and commercial viability of MEA-based CO<sub>2</sub> capture catalyzed by IONPs, particularly suitable for deployment in large-scale CO<sub>2</sub> capture systems in high-CO<sub>2</sub>-emitting industries. |
