A gas mixture containing 1.5 mole % A and 98.5 mole % B is to be contacted by a pure liquid in a packed absorption column. The concentration of A in the gas stream 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 liquid rate used is twice the minimum. The mass transfer coefficient for the gas phase is kya = 100 kgmol/h m^3 and for the liquid phase kxa = 2000. The equilibrium relationship can be represented as yA=9.95 xA
a) what is the operating line relationship?
b). What is NOG?
c). What is HOG?
d) What is the packed height of the column?
