Chapter 6, Problem 6.41P
An important parameter in the design of gas absorbers is the ratio of the ?ow rate of the feed liquid to that of the feed gas. The lower the value of this ratio, the lower the cost of the solvent required to process a given quantity of gas but the taller the absorber must be to achieve a speci?ed separation.
Propane is recovered from a 7 mole% propane—93% nitrogen mixture by contacting the mixture with liquid n-decane. An insigni?cant amount of decane is vaporized in the process, and 98.5% of the propane entering the unit is absorbed.
(a) The highest possible propane mole fraction in the exiting liquid is that in equilibrium with the propane mole fraction in the feed gas (a condition requiring an in?nitely tall column). Using Raoult’s law to relate the mole fractions of propane in the feed gas and liquid, calculate the ratio 
corresponding to this limiting condition.
(b) Suppose the actual feed ratio 
is 1.2 times the value calculated in Part (a) and the percentage of the entering propane absorbed is the same (98.5%). Calculate the mole fraction of propane in the exiting liquid.
(c) What are the costs and bene?ts associated with increasing 
from its minimum value [the value calculated in Part (a)]? What would you have to know to determine the most cost−effective value of this ratio?
