"Effect of the liquid phase viscosity (0.7 to 25 mPa s) and surface tension (33 to 65 mN m-1) on hydraulic and mass transfer characteristics in a bubble column with an up-flow ejector-type gas distributor was studied. The coalescent character of the aqueous batches was changed by addition of a polymeric thickener, sucrose and an alcoholic foam breaker. Mass transfer was studied using steady-state physical absorption of air. Better performance of the ejector with swirl body for all tested liquid batches was achieved. Gas hold-up in the bubble column increased with increasing viscosity and surface tension in all batches. Mass transfer coefficient in the ejector decreased with increasing viscosity by 60% maximally in the maximum viscous coalescent batch. It was correlated within +_10% using the gas monodispersion model. Mass transfer coefficient in the column decreased with increasing viscosity by 30% maximally in the same coalescent viscous batch. It was correlated with large relative error, +_27%." . "P(GA104/97/1170), Z(AV0Z4072921)" . .
