co2 capture enhancement in a rotating packed bed reactor with different blade packing structures

In this paper, the mass transfer enhancement in a typical rotating packed bed reactor (rpb) with blade packings for carbon dioxide absorption into monoethanolamine (mea) was investigated# also, the effect of packings structure on the mass transfer coefficient and gas absorption efficiency of carbon dioxide were investigated at different rotational speeds# for this purpose, a plexiglass reactor with a stainless steel blade packings was used, and in order to investigate the effect of packing structure, angular blade packing with 30 degree angle to radial axis, and non-angular blade packing (zero degree relative to radial axis) were compared with each other# the concentration of monoethanolamine and carbon dioxide were considered 1 mol / l and 2 vol%, respectively# the overall volumetric gas-side mass transfer coefficient and absorption efficiency at different rotational speeds in both rpbs with angular blade packings and non-angular blade packings were investigated# the effect of rotational speed on the gas-side mass transfer coefficient and carbon dioxide absorption efficiency was also evident in both packings# the obtained results of the experiments showed that the angular blade packings had a significant effect on increasing the gas-side mass transfer coefficient and improving the carbon dioxide absorption efficiency in the rpb reactor in comparison with the non-angular blade packings#
