Testing the Well-Mixed Model for a Gas-Liquid Stirred Ozonization Reactor

Abstract

A “well-mixed” model was developed for a semi-batch gas-liquid reactor designed to study the mechanisms of ozonation of organic compounds in aqueous media, and tested against unsteady-state absorption data. In the (experimental range examined for the superficial gas velocity (v)Q < 0.30 cms(1),) this model fairly describes the fluid dynamic behavior of the reactor for stirring speeds not greater than about 400 rpm. To minimize the effects of the physical factors on the computed kinetic parameters, the kinetic experiments should be carried out in these operating conditions.
