This technology is based on the chemical reaction and equilibrium between the sour gases, CO2 and H2S, and the ethanol amine. In this example, we are going to determine the number of units of transmission for a column that treats a gas flow of 50,000 kg/h m with a mass composition of 0.045 H2, 0.627 CO, and 0.328 CO2 in order to remove 99.9% of the CO2 present for its use in the production of second-generation bioethanol. The flow of solution is 1000 kmol/h m. The equilibrium data for the CO2 absorption in monoethanol amine (MEA) can be found in Joe et al. [7].
