Well 13 at Watapitae is contaminated with 440 g - L-1 of tetrachloroethylene (perchloroethylene). The water must be remediated to achieve a concentration of 0.2 g-L-1 (the detection limit). Design a packed-tower stripping column to meet this requirement using the following design parameters. Note that more than one column in series may be required for reasonable tower heights. Henry's law constant = 100 x 10m.atm.mol- KL 13.5 x 10 Air flow rate 15 m.s-1 Liquid flow rate=0.22 m. s- Temperature = 20C Column diameter may not exceed 4.0 m Column height may not exceed 6.0 m
