Sparge ring

Stirred tanks are often used for gas-liquid reactions. The usual geometry is for the liquid to enter at the top of the reactor and to leave at the bottom. The gas enters through a sparge ring underneath the impeller and leaves through the vapor space at the top of the reactor. A simple but effective way of modeling this and many similar situations is to assume perfect mixing within each phase. [Pg.382]

The recommended sparge ring to impeller diameter ratio is 0.65-0.8, while the ring sparger orifice diameter is in the range of 2-10 mm, and the gas velocity through the orifice is between 15 and 30m/sec. Pressure drop across a perforated disperser or orifice is estimated by the conventional orifice equation ... [Pg.963]
