A column packed with 1-in. ceramic rings is to be designed to absorb component X from an air stream using pure water as a solvent at TC. The gas entering with mole fraction y of component X and it is desired to recover R percent of X. The total pressure is constant at 1.0 atm absolute .The rate of water used will be N times the minimum flow. The total air flow rate is V mole air/hr-m column cross-sectional area. The column cross section S= 1 m. Perform the following tasks 1) Use at least 6 points to draw the operating line. 2) Calculate number of stage graphically. 3) Calculate the height of the column using local mass transfer coefficient Equilibrium data for A- water system at 30C 0 0 0.003 0.005 0.15 0.25 0.007 0.36 0.009 0.45 0.013 0.66 0.015 0.017 0.76 0.86
