Abstract


An investigation was conducted on the critical gas velocity and applied power for complete suspension of solid particles in QVF hemispherical bottom gas sparged vessel of 0.46 m inside diameter and 1m height. The operating conditions used; particle size 63-90, 90-125, 125-180 and 180-250 μm, height of liquid level to vessel diameter ratio 0.7, 0.9, 1.1 and 1.3, weight of solids 0.4, 0.8, 1.2 and 1.6 kg. Single ring sparger with holes 1 mm diameter, different gases (air, helium, argon and carbon dioxide), water, kerosene and non-Newtonian liquids (four different concentrations of carboxyl methyl cellulose solutions) were used. Electro-resistivity probe was used to measure the hydrodynamic parameters included bubble rise velocity, bubble diameter, bubble frequency, number of bubbles and gas hold-up
