Assume the reaction of caustic and methyl mercaptan in Exercise 15.1 removes 100% of the mercaptan. Using Equation 15.2, how much air (lbm/h, kg/h) is needed to regenerate the caustic solution

Exercise 15.1

Using Equation 15.1, how much 15% by weight caustic (molar mass = 40) solution must be circulated (lbm/h, kg/h) to remove 22 lbm/h (10 kg/h) of methyl mercaptan (molar mass = 48) from an NGL mixture?
