Question:

We are adsorbing dichloromethane from air into water at $25^{\circ} \mathrm{C}$ and $10.0 \mathrm{~atm}$. pressure in a countercurrent absorber. The inlet vapor flow rate is 150 $\mathrm{mol} / \mathrm{minute}$. The inlet gas is $0.0025 \mathrm{~mol}$ fraction dichloromethane, and we want an outlet mol frac in the gas of 0.00016 . The entering solvent is pure water. What is the minimum solvent rate? Equilibrium data are in Table 12-2.
