Design an air stripping column to remove TCE from water (i.e. determine the stripping factor, the height and number of transfer units, and the height of the packing in the column). The initial concentration of TCE is 1.3 mg/L and this must be reduced to 75 µg/L. Use the following criteria: water flow rate of 350 gal/min; air to water ratio of 70; water temperature of 16°C; air temperature of 23°C; column diameter of 2 ft; 2-in Intalox saddles for packing material; liquid mass transfer coefficient of 20.4 cm/hr; design safety factor of 20% ; and tower height(s) between 1-15 m.
