Problem 3 only (not a graded question)
PROBLEM 2 A packed tower with an inside volume of 300 ft³ is to be used for an ammonia absorption under such conditions that Kaa = 2.8 lbmol/h atm ft³ and Henry's law is applicable to the ammonia solution. The pressure difference driving force at the top of the column (p-p*) is 0.009 atm, and the pressure difference driving force at the bottom of the column is 0.090 atm. If 550 lb of ammonia, in addition to the inert gases, enters the tower per hour, what percent of the entering ammonia will be absorbed? PROBLEM 3 Estimate the diffusivity of acetic acid diffusing through air at 298 K at 2 atm using the Fuller- Schetller-Giddings method. ANSWERS: Lmin No. of plates Height of tower % NH3 absorbed Diffusivity Answer Maximum Points 50 50 50 50 50 Actual Points
