Problem 5. A gas stream containing 8 mol % species A is sent to an absorption column (operated at 10 atm) that uses water as absorbent. Assuming that the water flow rate is 120 times the gas stream flow rate, constant molar overflow (CMO), and linear equilibrium line in the composition range of interest, use the graphical method to determine the number of theoretical stages needed to remove 90% of the A in the gas stream. Note that the saturation vapor pressure for species A is 880 atm. The activity coefficient of species A in the liquid phase is assumed to be 1.

![Problem 5. A gas stream containing 8 mol% species A is sent to an absorption column (operated at 10
atm) that uses water as absorbent. Assuming that the water flow rate is 120 times the gas stream flow rate,
constant molar overflow (CMO), and linear equilibrium line in the composition range of interest, use the
graphical method to determine the number of theoretical stages needed to remove 90% of the A in the gas
stream. Note that the saturation vapor pressure for species A is 880 atm. The activity coefficient of
species A in the liquid phase is assumed to be 1.
Hint: it is easier to draw the equilibrium line and operating line in Excel to ensure accuracy. Also, we are
not interested in the entire composition space (in which the linear VLE assumption will no longer be
valid), so it is important to draw the McCabe-Thiele plot only in the composition region of interest to
ensure higher accuracy of the graphical method.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe2b52438-2635-470c-baa2-f7fbb13e3290%2Fc70997c8-cdf0-4367-b889-8619b741e663%2F6la2u5_processed.jpeg&w=3840&q=75)
