Performance of Multi-Plunging Jet Absorber Using Liquid Jets Containing Small Solute Bubbles

The effects of structural factors in nozzles having a gas sucking type bubble generator and the number of nozzles for a multi-plunging jet absorber using liquid jets containing small solute bubbles on gas-liquid interfacial area and mass transfer were investigated. It was found that the volumetric liquid phase mass transfer coefficient (k L a) T of the absorber increased with increasing nozzle number. The mass transfer performance of this absorber was comparable to that of other high performance gas-liquid contacting devices. A two-region model was found to be applicable to the mechanism of liquid phase mass transfer in the multi-plunging jet absorber.
