Simultanoeus determination of vapour- and liquid- side volumetric mass transfer coefficients in distillation column

Original language description

The method for the determination of kL a and kV a in distillation column consists in afitting of the concentration profile along the column obtained by the integration of a differential model to the experimental one. Preliminary test of the method is pre-sented using concentration profile measured in the binary distillation of the ethanol-water system at total reflux on metal Pall Ring 25 mm. The distillation is modelled as a simul-taneous heat and mass transfer process and the mathematical model includes mass and energy balances and the heat and mass transfer equations. By using the Maxwell -Stefan flux expressions the convective transport contributions have been considered in the transfer equations. Vapour and liquid phases are supposed to be at their saturated temperatures along the column. Concentration and temperature dependent physical parameters and the liquid phase thermodynamic non-idealities have been taken into account. The distillation mass transfer coefficients in the liqu
