Abstract

In this paper, a semi-industrial detergent is used to remove carbon dioxide. Also, nickel oxide nanoparticles and functionalized carbon nanotubes with surfactant (SDS and CTAB) have been used. The findings of the possible DLS and Zeta experiments have shown that the nanoparticles used in this paper are stable in the vicinity of the surfactant and that their surface charges are sufficient to keep the nanoparticles from binding together in the base fluid. Also, the effect of alternating and constant magnetic field on pressure drop in Ventura detergent bottle, carbon dioxide adsorption, molecular flux of mass transfer of carbon dioxide adsorption mass and wasted amount. The solvent was examined. The results showed that by reducing the flow of air entering the venture detergent, the amount of solvent loss is reduced and also the addition of nickel oxide nanoparticles and functionalized carbon nanotubes with surfactant (SDS and CTAB) increases carbon dioxide uptake. The highest adsorption and molar flux of mass transfer occurs when a mixture of nickel oxide nanoparticles (25%) and carbon nanotubes (75%) is used in the presence of CTAB surfactant at a concentration of 5% by mass. Then, by presenting an experimental model by neural networks, the experimental results were proved.
