Profile method? for the measurement of kLa and kVa in distillation column. Validation of ratebased distillation models using concentration profiles measured along the column
Original language description
The "profile method" enables the determination of vapor- and liquid-side volumetric mass transfer coefficients kVa and kLa by comparing the concentration profiles measured in both phases in a distillation column with the simulated profiles. The method isbased on the fact that the shape of the concentration profiles along the column depend significantly on the distribution of the mass transfer resistance between the liquid and the vapor phases. This makes possible the measuring of kLa and kVa directly in the distillation columns, in the same manner is possible in absorption columns, and therefore to validate the distillation models more conclusively than by means of comparing the experimental and calculated HETP-values. The coefficients were measured on structured packing Mellapak250Y. A small axial mixing of phases on this type of packing enables the use of a plug flow model for both phases. Three distillation systems, methanol ethanol, ethanol-propanol and methanol-propanol, were use
