In the Aspen simulation, sodium carbonate and sodium bicarbonate are used to absorb CO2; the Flash 2 model is employed, and the electrolyte NRTL approach is used for property analysis. Why is the amount of CO2 absorbed in the liquid phase higher than that under actual production conditions?

It is estimated that Aspen’s calculations are based on an idealized scenario in which CO2 is completely absorbed; in reality, the efficiency of the process is not 100% as good
