抄録

An experimental and a theoretical study were performed on the chemical absorption of NH3 or SO2 in a wetted-wall column. It was found that the force induced by mass flux acts to compress the stream lines toward the liquid film and to promote gas absorption.<BR>When these phenomena are significant, great difficulty may be encountered in a quantitative evaluation of the absorption process by experiments alone, owing to the change of total flow rate and the existence of density convection due to the density distribution.<BR>Considering the variation of physical properties and the change of flow rate, the momentum and diffusion equations were solved by the finite difference technique. The results can also express the absorption processes quantitatively at high mass transfer condition.
