Enhanced Carbon Dioxide (CO2) Absorption using Fe2O3-Loaded MEA/TEA Nanofluids: A Statistical and Experimental Study

Abstract

CO2 has the lion's share of the gases that contribute to global warming. Consequently, the accumulation of this gas in the atmosphere has a detrimental impact on the life of all types of creatures. This paper addresses the application of magnetic nanofluids for CO2 by absorption removal approaches. A novelty of combining Fe2O3 nanoparticles were suspended in the base fluid of MEA and TEA using ultrasound. The effects of nanoparticle sizes (60, 80 and 100) nm, volume percentages (0.01%, 0.05% and 0.1%), and magnetic stirring speeds (1 and 4) rpm, were investigated on the absorption process. To identify the best condition of the absorption process applying nanofluid, the approach developed by Taguchi was applied. The ANOVA analysis demonstrated that nanoparticle concentration has a major impact on the absorption rate, while the size of the particles has relatively minor influence. The experimental results showed that with a magnetic speed of 4 rpm, by raising the concentration of nanoparticles from (0.01% to 0.1) vol. %., the absorption rate improved by 28%.
