As the primary phase in the development of multicomponent mass transfer theory, equations are derived which predict the rate of mass transfer of each species from an interface to a ternary gas mixture in turbulent flow for equimolal‐countercurrent transfer and for transfer with one of the three gases stagnant. The mass transfer equations obtained, regardless of whether a film, Prandtl‐Taylor, or modified Chilton‐Colburn model is used, differ in form from the usual binary equations and predict qualitative as well as large quantitative differences between binary and ternary transfer. A criterion is obtained which any consistent multicomponent mass transfer theory must satisfy, and although the ternary film and Prandtl‐Taylor models satisfy this criterion, the modified ternary Chilton‐Colburn model does not.
