Vapour- and liquid-side volumetric mass transfer coefficients measured in distillation column. Comparison with data calculated from absorption correlations.

Original language description

Volumetric mass transfer coefficients in liquid and vapour phases in distillation column were measured by the method consisting of a fitting of the concentration profile of liquid phase along the column obtained by the integration of a differential modelto the experimental one.The mathematical model of distillation process includes mass and energy balances and the heat and mass transfer equations.The film model flux expressions with 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.Effect of changes of phase .ows and physical properties of phases on the mass transfer coefficients along the column and non-ideal thermodynamicbehaviour of the liquid phase have been taken into account.The concentration profiles of liquid phase are measured in the binary distillation of the ethanol -water and methanol -ethanol systems at total reflux on metal Pall Rings and Inta
