Mass transfer in packed columns, wetted wall towers and from plane horizontal surfaces has been shown to be adequately predicted by theory, providing extraneous effects are handled correctly. The mass transfer can be correlated using a Gilliland‐Sherwood type formula in which the relative velocity between the phases at the interface is the important parameter. The correlation applies regardless of the geometry of the system, and provides a general mechanism for estimation of the mass transfer within equipment. Such an approach allows for estimation of the actual transfer taking place in mass transfer equipment without resource to estimation of stage efficiencies, and should eliminate the need, for example, for the Murphree stage efficiency.
