The Effects of Isobutanul Addition on Bubble Size, Gas Holdup, Interfacial Area, Bubble Coalescence, and Transition Concentration in Dispersion Column

Fadi Zakariya Hanna and Ribwar Kermanj Abdulrahman
Abstract—The bubble coalescence and the transition concentration in a dispersion column have been experimentally studied in this study work by adopting isobutanol-water mixture as a liquid phase and air as a gas phase. The experimental work included the following experimental variables; the weight percent of isobutanol in water and superficial gas velocity of air. The using of two distributors single-orifice and multi-orifice, bubble size, gas holdup and gas-liquid interfacial area are measured. The experimental results have showed that the isobutanol transition concentration is successfully correlated as a function of superficial air velocity, ct=0.072079-0.006408Ug+0.000425Ug 2-0.00001Ug 3. This equation gives mean deviation of 4.501%.

Index Terms—Gas-liquid dispersion column, bubble coalescence, transition concentration.
