Vapour-liquid interface and

Due to chemical conversion in the liquid-phase mass transfer film the mass flux of A at the vapour-liquid interface and the mass flux of A at the boundary between this film and the liquid bulk will differ. Figures 9(a) and (b) show the values of these fluxes as a function of the reaction rate constant ko for equilibrium constants K = 1 and X = 100. The... 

Fig. 9. The molar flux of component A at the vapour-liquid interface (°) and at the boundary between mass transfer film and liquid bulk (S) as function of reaction rate constant in case (a) the mass transfer coefficients are equal and (b) the mass transfer coefficients are different.

Also in this configuration, the membrane acts purely as a support for a vapour-liquid interface and does not contribute to the separation mechanism. Furthermore, the flux is independent of the temperature of the sweep gas. It should be noted that the effect of the feed temperature, solute concentration and velocity on the flux are similar to their effect in DCMD (Lawson and Lloyd, 1997). As in AGMD, this configuration is particularly useful for the removal of volatile compounds (other than water) or dissolved gases from liquid streams.
