The influence of viscoelasticity on gas hold‐up and the volumetric mass transfer coefficient in a bubble column is discussed and examined experimentally. It was found that the gas hold‐up increased due to an increase in the number of entrapped very small bubbles formed because of the elasticity of the liquid. On the other hand, a decrease in volumetric mass transfer coefficient due to the fluid elasticity was observed. Qualitative effects of an antifoam agent and a draft tube on the performance of the bubble column with viscoelastic fluids were also examined.
