Experimental results of mass transfer in air-water system with a dispersed immiscible organic liquid in a bubble column 0.076 m in diameter for seven different organic liquids at various hold-up are presented. Experiments are carried out at gas superficial velocity in the range 0.0052-0.026 m/s at 293 K. The volumetric mass transfer coefficient, kLa is determined by dynamic gas absorption technique. Overall gas hold-up is also measured. Slight addition of n-decane, dodecane and n-heptane in air-water medium significantly enhances mass transfer from the gas phase, to the continuous aqueous phase whereas toluene, anisole and 2-ethyl- 1-hexanol retard mass transfer.
