| Abstract: | A very simple slug apparatus capable of forming a slug long enough to make the inherent end effect for mass transfer negligible, has been developed. Continuous phase mass transfer in a stable laminar liquid-liquid flow was studied for the dissolution of an MIBK slug into water flowing as a continuous phase. The observed mass transfer coefficients were shown to be in good agreement, over a wide range of contact time between the two phases, with the penetration theory or the Hatta theory, which allows for the effect of a finite thickness and velocity distribution in the relevant phase. |
