10. Adsorption column design (10 points) An absorption tower is used to absorb ammonia from air using pure water with counter- current operation. If the gas flow rate G=0.02 kmol/m's, inlet ammonia fraction y) = 5%, outlet mole fraction xh = 5%, ya = 0.25%. The equilibrium relation is y* = 0.95x and the overall gas mass transfer coefficient Kya = 0.04 kmol/m's. i) Calculate the height of the tower. Recall that h = HOG NOG Youtdy Kya'yin yery (Hint: when the absorption factor m = 1, y* y is a constant at any cross-section of the tower) ii) Under certain conditions, it might be economical to partially recycle the liquid stream (represented by LR in the following figure). Calculate the maximum value of Lr in this case (Hint: at maximum Lr, chemical equilibrium will be reached at the top of the column). Gy. L, X LE H G, L, X
