Estimation of hydrodynamic characteristics of sparged bubble column for electrolytes and alcohol

摘要

The present work highlights the effect of various parameters like superficial gas velocity (V{sub}G) and height to diameter (H/D) ratio on fractional gas holdup (ε{sub}G) in bubble column. For this purpose, experiments were conducted in 0.14 m ID column having 2 m height. Water, air and alcohol were used as liquid and gas phase, respectively. The column with ring sparger having 67% active area is used as sparger for dispersing the dispersed phase into the continuous phase. For the optimized sparger plate, the effect of various parameters on fractional gas holdup for air-water system and alcohol was studied. Also the effect of various parameters on fractional gas holdup for air-water with Alcohol like Methanol, Ethanol and Butanol of various concentrations were studied and reported.
