Effects of Adding Alcohols, Electrolytes and Carboxyl Methyl Cellulose (CMC) on Design Parameters in Internal Loop Airlift Bubble Column

The effect of gas velocity, liquid-phase properties, solid-particle concentration and the static liquid height on gas hold-up (ɛg) and mass transfer coefficient (KLa) were studied in a three phase internal loop airlift bubble column (ILBC) (the ratio of the draft tube to column diameter equal to 0.5...
