A Study of Axial Mixing Influence on the Mass Transfer Transferability from Absorption to Distillation Conditions
Original language description
Our paper assesses success of the recalculation of the mass-transfer data from absorption to distillation conditions for the Mellapak 250Y structured packing and two random packings (Pall rings 25mm and Intalox saddles 25mm). The tests of the recalculation procedure are namely focused on the effect of taking into the account of the axial mixing of the liquid phase or acceptance of the usual assumption of the plug flow. The absorption data in the form of the volumetric mass-transfer coefficients were either overtaken from the literature or were measured in the absorption column of inner diameter of 0.29m using proven aqueous test systems. The distillation data in the form of the HETP were measured under the total reflux in the 0.15m atmospheric column using C6/C7 and methanol/n-propanol systems. The measurement of the hydrodynamic parameters revealed significant degree of the liquid-phase axial mixing for all the packings, while the total liquid hold-up were found to be comparable. The
