A gas mixture of A & B containing 1.5 mole % A and 98.5 mole % B is to be contacted by a pure liquid in a packed absorption column. A gas stream concentration is to be reduced to 0.5 mole %.( the cross sectional area of the column is 1 m^2, and the vapor rate 200 kgmol/h.) The mass transfer coefficient for the gas phase is kya = 100 kgmol/h m^3 for the liquid phase kxa = 2000. The liquid rate used is twice the minimum, the equilibrium relationship can be represented as yA=9.95 xA then determine what is HOG, operating line relationship, NOG and packed height of the column?
