Clean charcoal is used to adsorb an acetone impurity present in air. The charcoal-air suspension enters an adsorption column at a flow rate of while the air flow rate is
. The goal is to remove 90% of the impurity. The inlet gas stream carries
of impurity per kg of air. The Langmuir equation is used to describe the equilibrium between the solid and the gas:
