From overall mass transfer equation,
( )
*
A y AG A N  K y  y
one can write for packed
tower as
NA=Ky(y-y*)
Then,
= −

1− (−
∗)
(4.10)
where, y* is solute concentration in gas phase that is capable of remaining in
equilibrium with a liquid having a bulk concentration of x.
Therefore,

Graphical integration of right hand side of Equation (4.11):
Operating line AB is drawn in xy plane. Any point (x,y) is taken in operating line.
A vertical line is drawn upto equilibrium line to get y*.
