Problem 1. (40 points) You are designing a packed bed liquid/gas absorption tower for the removal of component A from a stream of air. Air enters the column with a mol fraction of 0.02 and leaves with a mol fraction of 0.005. Pure Water enters the column and leaves with a mol fraction of 0.01. The equilibrium follows Henry's Law type behavior: y = 1.2%. a) Plot the equilibrium line, operating line, and points P., P, E, E, D, and D, on the following chart: (10 points) 0.025 0.02 0.015 0.01 0.005 0 0 0.005 0.01 0.015 0.02 b) Given that k, = 3.5 x 10 kgmol/smand k, = 8.6 x 105 kgmol/sm, determine the interfacial compositions at the top of the column (x, andya) and plot point M, on the chart above. You may assume dilute conditions. (15 points) Problem 1 continued c) Determine the height of the overall transferunit in the gas phase (Hog) in meters, the number of overall transfer units in the gas phase (Noc) and the total height of the packed column (z) in meters. S=2.5 m2; V = 0.23 kgmol/hr. (15 points)
