Abstract
An experimental and a theoretical study of gas-phase multicomponent mass transfer under condition of high mass flux were performed, for the simultaneous chemical absorption CH2NH3 and of NH3 in a wetted-wall column.
It was found that interaction between. diffusion fluxes in the multicomponent system becomes more significant with increasing concentration of absorbed gases and tends to promotemass transfer. High mass flux and density-driven convection also have strong influence onthe transport characteristics.
Considering the variation of physical properties, the change of flow rate and multicomponent diffusional interaction, the momentum and diffusion equations were solved by the finite difference technique. The calculated mass transfer rates coincide with the experimental ones.
