Find the height of a packed tower that uses air to strip hydrogen sulfide out of a water stream containing only 0.2% H2S. In this design, assume that the temperature is 25 C, the liquid flow is 58 kg/sec, the liquid out contains only 0.017 mol% H2S, the air enters with 9.3% H2S, and the entire tower operates at 90 C. The tower diameter and the packing are 50-cm and 1.0-cm Raschig rings, respectively, and the air flow should be 50% of the value at flooding. The value of Ka is 0.23 sec-', and the Henry's law constant (yh,s/XH,s) is 1,440.
