SULZER BX GAUZE - FLUID-DYNAMICS AND ABSORPTION OF ACID CASES

The aim of this work is a fluid dynamics study of the structured packi ng Sulzer BX gauze. A new model is proposed which, on the basis of a k nowledge of the dynamic component of the liquid holdup, permits calcul ation of the fraction of the geometric area of the packing that effect ively participates in the mass transfer. Both the metal and plastic ve rsions of the packing are studied. Experimental data are supplied on t he absorption of pollutants such as HC1 and SO2 by aqueous solutions o f NaOH in columns in cocurrent operation. The results obtained by the proposed model are in good agreement with experimental data obtained b y the present authors as well as with experimental data published in t he literature.
