10.7. ABSORPTION OF CONCENTRATED MIXTURES IN PACKED TOWERS

In Section 10.6F simplified design methods were given for absorption of dilute gases in packed towers when the mole fractions in the gas and liquid streams were less than about 10%. Straight operating lines and approximately straight equilibrium lines are obtained. In concentrated gas mixtures the operating line and usually the equilibrium line will be substantially curved and and may vary with total flows. Then the design equations (10.6-17)–(10.6-20) must be integrated graphically or ...
