  4. Abstract:
  5. In this article, the influences of ferrofluid and magnetic field on the reactive absorption in packed-bed contactors have been investigated. Because of importance of carbon dioxide emission as a global concern, absorption of carbon dioxide was chosen to investigate these effects. In this regard, multitube approach was applied to model the contactor. The simulation results were validated against experimental data reported in the literature in the absence of nanoparticles and magnetic field and good agreement was obtained. Moreover, influences of various operating conditions on the contactor performance were investigated. It was found that for 3.4 vol.% of magnetic nanoparticles (MNPs), the local mass-transfer coefficient for the gas phase at the top of the absorption column increases about six times relative to that obtained in the absence of magnetic field and MNP and an increase of 117% in the average Sherwood number value for the gas phase was obtained. Furthermore, it was found that using MNPs and applying a magnetic field simultaneously enhance the performance of industrial chemical absorption systems. © 2016 The Korean Society of Industrial and Engineering Chemistry
