Hydrodynamics and mass transfer in bubble column: Influence of liquid phase surface tension [PDF]
, 2007 According to literature, few experiments are performed in organic solvents which are mostly used in commercial gas–liquid reactors. However, it is commonly accepted that data obtained in aqueous solution allow to predict the surface tension effects, and ...
