Abstract
Previous chapters have only considered the behaviour of pure single component fluids during evaporation and condensation. However, in the petrochemical industries in particular, many processes involve the evaporation (and condensation) of binary (n = 2) and multicomponent (n > 2) mixtures where n is the number of components. In the boiling of binary and multicomponent mixtures, the heat transfer and the mass transfer processes are closely linked, with the evaporation rate usually being limited by the mass transfer processes. This is significantly different from single-component systems where interfacial mass transfer rates are normally very high.
