The relation holds also for multicomponent mixtures, just that in this case subscript i is required.

It becomes difficult to extrapolate correction factors for a single chemical to multicomponent mixtures.

For purifications, in particular the isolation of an intermediate single component or a fraction out of a multicomponent mixture, the SMB is not as ideally suited.

AIOMFAC online-model: calculator for activity coefficients of inorganic ions, water, and organic compounds in aqueous solutions and multicomponent mixtures with organic compounds.

To consider multicomponent moisture solid in a vibrating fluidized bed drier, a model was used to assess the characteristics of drying a thin layer of particle which was wetted with a multicomponent mixture.

In such refineries, the crude oil feedstock is a complex, multicomponent mixture that must be separated, and yields of pure chemical compounds are not expected, only groups of compounds within a relatively small range of boiling points, also called fractions.
