ASPEN PLUS simulation model for CO2 removal with MEA: Validation of desorption model with experimental data

A good agreement is observed between experimental data and the simulation results of the chemical absorption process presented here. The model shows an AARD (average absolute relative deviation) of 9.2% for the CO2 stripped (kg/h) for the tested 78 experimental runs. The simulated temperatures of the liquid flux leaving the reboiler show a deviation of 3.3% compared with the experimental data. The deviations on the estimation of the CO2 stripped show some dependency on the CO2 loading in the rich amine flux entering the desorber. However, the deviations are independent on the temperature of the rich amine.
