A toxic organic is to be removed from wastewater using a packed stripper. The initial mole fraction of the organic is 0.002 which must be purified to a mole fraction of 0.00005. The flowrate of water to the column is 7200 kmol/hr. Use the following data: K_ya = 1094 kmol/m³*hr ; y=37x (equilibrium data). You may assume dilute concentrations.

A.) What is the minimum air flow rate needed to achieve this separation?

B.) Using an air flowrate of 1.5V_minand a tower diameter of 1 m, find the height of the packing necessary to achieve this purification.
