Theset up is capable to study the loading and flooding characteristics. It is apacked column packed with rasching rings where the air is counter currently fedto the column. Liquid holdup in the column increases the weight of column andalso reduces the effective porosity of packing. This reduction in porositydecreases the gas velocity, increases the pressure drop and changes the valueof mass transfer co-efficient. The water is fed from the top of the column andloading & flooding characteristic are observed on various flow rates of airand water. The apparatus is closed circuit type provided with suitable capacitytank, pump, necessary pipe lines walls & rotametres for water & air tomeasure the flow rate of fluids.
