A cocurrent flow of pure gaseous SO 2 and liquid H 2 O was used to fluidize particulate zinc in order to produce industrial concentrations of zinc hydrosulphite, ZnS 2 O 4 . Based on transport phenomena and reaction kinetics, measured concentration profiles of both absorbed SO 2 and reacted Zn, as well as mean solid holdups, were best predicted by a combined bubble‐wake and axially dispersed plug flow model.
