โœฆ Synopsis

Two stirred transfer cells were used for studying the rate of mass transfer across an interface between two liquid phases, in order to investigate the influence of molecular diffusion on the mass transfer. The systems ethyl acetate-water and n-butanol-water at 2.5 "C provided a wide range of diffusion values. The relationship between mass transfer coefficients and the variables was obtained by dimensional analysis. The comparison of observed and calculated results shows

In Part I of the article there were reported profound differences in behaviour between the bottom and the upper stages of a multiple-impeller vessel under gassed conditions: the volumetric mass transfer coefficient, kLa, for the bottom stage was by up to 50% lower than that for the upper stages. A p
