Question: An aqueous solution containing 2 mole percent of a volatile organic is to be stripped with steam. This aqueous solution is fed to the top of a packed column and steam is fed to the bottom. Ninety-five percent of the entering organic is to be stripped from the water solution by the steam. The equilibrium relation for this situation is given by

y_A = 0.1√x_A

In actual operation WG remains approximately constant

(a) Plot the equilibrium line. Determine the maximum value of L/G which is possible for column operation.

(b) Using the actual operating value of WG which is equal to 0.5, plot the operating line. Find the outlet concentration yl for this case. Write tbe algebraic equation for the operating line.

(d) Given that Kx has been found experimentally to be 20 lbmolh ft3 for the above conditions, find noL for a liquid rate of 500 lbmoVh ft2 and determine the height of the packed section.
