Résumé

In recent years, absorption of carbon dioxide using nanofluids has increasingly gained attentions due to its unique advantages. In this study, the absorption of carbon dioxide using Sulfinol-M based nanofluids were investigated. Functionalized MWCNTs and Fe3O4 nanoparticles were dispersed in the absorbent in order to study their effects on absorption rate and equilibrium amount of absorption using a high pressure vessel equipped with a magnetic stirrer. The effects of different parameters including nanoparticle type, nanoparticle concentration in Sulfinol-M and initial pressure of CO2 in gas phase were investigated. The obtained results revealed that the presence of both nanoparticles in the based solvent can enhance the rate of absorption and also the equilibrium solubility to a maximum amount of 46.7% and 23.2%, respectively. MWCNT shows better effects and it increases the solubility up to 7.3% more than Fe3O4 nanoparticle under the same condition. In addition, the possible mechanisms regarding mass transfer augmentation and equilibrium solubility enhancement are discussed.
