Abstract
We have developed a new type of absorber using a gas–liquid two-phase plunging jet, based on an ejector-type nozzle equipped with a perforated plate. One characteristic of an impinging gas–liquid two-phase jet is described by (k̅LA)T, the product of the liquid-phase mass transfer coefficient and the gas–liquid interfacial area in the gas bubble dispersed phase. We studied the dependence of this product on the structural configuration of the nozzle and investigated the mass transfer mechanism using a coaxial bi-zonal model. The theoretical results were in good agreement with the experimental results. The (k̅LA)T value for this absorber was found to be larger than that for a conventional single-phase plunging-jet absorber.
