The mathematical model of the process with different simplifying assumptions concerning heat and mass transfer was elaborated. In numerical calculations mass transfer resistances both in gas and liquid phases were considered. Experimental study was performed for 2-ipropanol-water system in the wide range of concentrations and temperatures. The comparison shows small effect of diffusional cross effects on mass transfer and selectivity.6 pagesPDFenUniversity of PretoriaHeat and mass transferMass fluxesFalling film evaporationBinary mixtureInerts in gasMass transfer resistances2-ipropanol-water systemPresentation
