A water cleanup operation involves stripping vinyl chloride from contaminated ground water at 25 °C and 850 mm. Hg using a countercurrent, staged stripper. The feed has 5.0 ppm(molar) vinyl chloride, and the outlet water contains 0.1 ppm (molar) vinyl chloride. Inlet air used for stripping is pure. For a liquid flow rate of L = 1 kmol/h , determine the following : Minimum gas flow rate in kmol/h. If the actual gas flow rate = 2.0 × (minimum gas flow rate) calculate the number of stages Henry’s constant (HB) for vinyl chloride = 1243. 84 atm.

Question
A water cleanup operation involves stripping vinyl chloride from contaminated ground water at 25 °C and 850 mm. Hg using a countercurrent, staged stripper. The feed has 5.0 ppm(molar) vinyl chloride, and the outlet water contains 0.1 ppm (molar) vinyl chloride. Inlet air used for stripping is pure. For a liquid flow rate of L = 1 kmol/h , determine the following :
Minimum gas flow rate in kmol/h.
If the actual gas flow rate = 2.0 × (minimum gas flow rate) calculate the number of stages Henry’s constant (HB) for vinyl chloride = 1243. 84 atm.
