FIG. 14-6 Relationship between equilibrium curve and operating curve in a packed absorber; computation of interfacial compositions.

FIG. 14-6 Relationship between equilibrium curve and operating curve in a packed absorber; computation of interfacial compositions.

where LM = molar mass velocity of the inert-liquid component and G'm = molar mass velocity of the inert gas; LM, L'M, GM, and G'M are superficial velocities based upon the total tower cross section.

Equation (14-11) is the differential equation of the operating curve, and its integral around the upper portion of the packing is the equation for the operating curve.
