Most industrial mass transfer processes consists in penetration of a component or several components from one phase to another through the interphase: extraction, absorption, distillation, drying, etc.
Mass transfer during penetration covers the following three stages:
- Mass penetration from the inside of the first phase to the interphase, i.e. to the film at the junction of ozone and liquid.
- Transfer of mass through the interphase – through the film.
- Mass penetration from the interphase to the inside of the second phase – from the film to the liquid.
