The influence of liquid rheology on the gas holdup in a simple bach bubble column was studied.
Aqueous solutions of Carboxymethyl cellulose (CMC) at 17˚C were used as a non-Newtonian
fluid. Air was sparged to a 0.11 m in diameter bubble column via a sieve plate, having 19 hole of 1
mm in diameter. The experimental data show that the total gas holdup decreases by increasing the
liquid apparent viscosity. A correlation for total gas holdup prediction in bubble column with non-
Newtonian liquid was proposed. It does require viscosity of liquid explicity
