Abstract Carbon neutrality is crucial in the fight against climate change, as it refers to a state which CO2 emissions balance with measures of removal and offsetting, effectively meaning no net increase atmosphere. This mandates that technologies for capture from flue gases technology utmost importance reducing greenhouse gas industrial sources. MEA very established solvent capture, but could be improved if nanoparticles are added make performance better. The primary objective study evaluate absorption efficiency combination RH-derived silica compare absorption–desorption rates nanoparticle-enhanced solution pure MEA. Adding RHSNp greatly rates. experiment showed an 83.33% using 22 wt% 0.5 (RHSNp), whereas 66.67% was observed without adding RHSNp. rate calculated 4.5 litres per hour. During desorption, stripping up 95% realized. These results demonstrate regeneration solution. research work has demonstrated potential enhance gases. It concluded can more effective absorb at increased compared usual suggest this promising approach incorporate into amine-based solvents process intensification benefits particularly prominent scalability application.
