Consider the interphase mass-transfer process for the chlorine dioxide, ClO2–air–water system. ClO2 gas (solute A) is sparingly soluble in water. The Henry’s law constant for the dilute solution of ClO2 in water is 0.00077 atm/(g mol/m3). At the current conditions of operation, the mole fraction of ClO2 in the bulk gas phase is yA = 0.040 and the mole fraction of ClO2 in the bulk liquid phase is xA= 0.00040. The mass density of the liquid phase is 992.3 kg/m3 and is not dependent on the very small amount of ClO2, dissolved in it. The total system pressure is 1.5 atm. Is the process gas absorption or liquid stripping? If the ClO2 partial pressure in the bulk gas phase is maintained at 0.06 atm, what is the maximum possible dissolved ClO2 concentration, g mol/m3, in the liquid phase that could possibly exit the process? If kx = 1.0 gmol/m2.s and kG = 0.010 gmol/m2 .s. atm,what is Ky, the overall mass-transfer coefficient based upon the overall gas phase driving force?

Consider the interphase mass-transfer process for the chlorine dioxide, ClO2–air–water system. ClO2 gas (solute A) is sparingly soluble in water. The Henry’s law constant for the dilute solution of ClO2 in water is 0.00077 atm/(g mol/m3). At the current conditions of operation, the mole fraction of ClO2 in the bulk gas phase is yA = 0.040 and the mole fraction of ClO2 in the bulk liquid phase is xA= 0.00040. The mass density of the liquid phase is 992.3 kg/m3 and is not dependent on the very small amount of ClO2, dissolved in it. The total system pressure is 1.5 atm.
