The exit gas from an alcohol fermenter consists of an air-C02 mixture containing 15 mol% CO2 that is to be absorbed in a 5-N solution of triethanolamine (free of CO2). If the column operates isothermally at 25C, if the exit liquid contains 78.4% of the CO2 in the feed gas to the absorber, calculate: a. Minimum gas to liquid ratio. b. Number of stages required if (L/V) = 1.5 (L/V)min ) L Y 0.003 0.008 0.015 0.023 0.032 0.043 0.055 0.068 0.083 0.099 0.12 X 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 0.1 0.11
