Gas-Liquid mass transfer in the jet reactor with liquid jet ejector

Abstract

Liquid-side volumetric mass transfer coefficients and effective gas-liquid specific interfacial areas were measured from the longitudinal distribution of oxygen concentration in gas phase by catalytic sulfite oxidation with air in the spouting and the calm sections, which were the lower and upper regions respectively in the jet reactor with liquid jet ejector. Both liquid-side volumetric coefficients and effective gas-liquid specific interfacial areas increased with the kinetic energy of the liquid jet, and their values in the spouting section were larger than those in the calm section. Further, effective gas-liquid specific interfacial area showed greater values than in other types of reactors, at a similar power supply per unit reactor volume. © 1983, The Society of Chemical Engineers, Japan.
