A gas feed at a rate of 100 kmol/hr containing 90% air and 10% acetone enters the absorber fill column. The column has a cross-sectional area of 0.2 m2 and operates at 20°C and 101.32 kPa. The stuffing used is the 1 in. intalox saddle type. The absorption process can remove 95% of the acetone present in the air. Under these operating conditions, the total solute mass transfer coefficient, Kya = 9.90 × 10−2 kmol m3/s. The acetone-water equilibrium data under these conditions are:

If Ls′ /Gs′ = 1.25 × (Ls′ /Gs′ )min, calculate:

a. How many moles of acetone are carried with the output of the absorbent liquid.
b. Filling height, in m
c. Theoretical plate equivalent height (HETP), in m
