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.
