16. Carbon dioxide is produced by recovering CO2 from flue gas. The flue gas is passed up though an absorber in contact with an aqueous solution of Na2CO3. The flue gas contains 20 percent (by volume)of CO2. The effluent gas from the absorber contains 9 percent CO2 (by volume). How many kg moles of flue gas are required to produce 1000Kg of CO2 if 90 percent of the CO2 absorbed is recovered as a product?
