Mass transfer characteristics of packing in a rotating packed bed

With a N 2 water system, the mass transfer process of two types of packing with different shape were experimentally studied in a rotating packed bed (RPB). The relations of volumetric mass transfer coefficient with rotating speed, liquid flow rate and gas flow rate were measured, and mass transfer characteristics of two packings were investigated. By comparing mass transfer coefficients of two packings, one packing that had better mass transfer performance was sorted out. The effect of specific area of packing on volumetric mass transfer coefficient was discussed further, and it was justified that gas liquid mass transfer intensification is primarily the result of great effective mass transfer area generated by liquid atomization. Finally, based on the experimental data, the empirical correlation equation of the mass transfer coefficient was derived by regression.
