Abstract
Today, the use of solvents containing nanoparticle to improve the rate of absorption of acid gases have been noticed by many researchers. In this study, the physical absorption of carbon dioxide in water nanofluid containing alumina nanoparticles in a wetted wall column was investigated. The central composite design of response surface methodology was used to analyze and optimize nanofluid performance system. In this regard, the performance of the absorption process was evaluated by measuring the liquid phase mass transfer coefficient based on independent variables including: nanoparticle concentration (0-1 g/l), nanofluid flow rate (100-300 ml/min) and fluid temperature (25-45 ℃). Using analysis of variance, a quadratic model was proposed to predict the mass transfer coefficient in the water-alumina nanofluid with R2 = 0.977. Results show that by adding 1 and 0.5 g/l of alumina nanoparticle in the water-based nanofluid, the gas absorption rate increases by 47 and 19%, respectively. The results indicated that increasing concentration of nanoparticle and fluid flow rate have the greatest effect on the mass transfer coefficient.
