The convective dispersion theory of Gill and Sankarasubramanian is extended to allow for multiphase mass transfer interactions in column‐type contactors, and for multisolute, reversible and irreversible, homogeneous and wall‐catalyzed heterogeneous chemical reactions in the individual phases. This theory can now be applied in any transverse average, not just the area average used in the past, and additional interactions between the phases not normally accounted for in the traditional axial dispersion model are indicated.
