| Abstract: | It is proposed that New VST cap unit mass transfer is composed of cocurrent and impingement.Mass transfer models of two parts and the relationship of the overall efficiency to mass transfer unit number of two parts are established. The effect of parameter of models on efficiencies are analysed. With single cap, the cap unit efficiencies without impingement and with impingement are measured. Empirical correlations for the number of two parts are given. |
