(A fermentation process produces a gaseous mixture containing CO2 and ethanol, with a molar composition of 92 percent CO2 and 8% alcohol. The ethanol must be recovered using water as the solvent in a counter-current absorption process (Figure 1). The gas mixture will enter the tower at a rate of 4000 m3 per hour at 25 degrees Celsius (298 degrees Fahrenheit) and 1.1 atm, while the solvent (water) will be supplied at a rate of 6500 kg/h at 298 degrees Fahrenheit. The required ethanol recovery rate will be 97.0 percent)
