A gas absorption unit is being utilized to remove carbon dioxide from air by absorption into water. The mole fraction of CO2 in air at the inlet is 0.2 and the flow rate of the gas stream is 100 l/min. It is preferred to remove 95 % of the CO2 in the gas stream. If pure water enters the column at a flow rate of 10 g/min, explain what is the mole fraction of CO2 in the liquid stream exiting the bed? You take 5 cc of this solution. Explain how many cc's of 1 M NaOH solution would be required to neutralize the solution?
