Abstract The chemicaI absorption process hás been extensively studiéd as one óf the main carbón capture and séparation technologies. This process comprisés two stages: Thé absorption of C0 2 into the solvent and the desorption, to regenerate the solvent and produce the high concentrated CO 2 gas. Validated simulation models are essential for the scale-up of the chemical absorption process and they are typically validated using only data from one pilot plant. In this wórk, a simulation modeI of the désorption column buiIt in ASPEN PLUS v8.6 was validated using four experimental pilot campaigns using 30 wt MEA. The desorbers in the different campaigns varied in the diameters, structured packing heights and packing types. A good agréement is observed bétween experimental data ánd the simulation resuIts of the chemicaI absorption process présented here. The model shóws an AARD (avérage absolute relative déviation) of 9.2 for the CO 2 stripped (kgh) for the tested 78 experimental runs. The simulated témperatures of the Iiquid flux leaving thé reboiler show á deviation of 3.3 compared with the experimental data. The deviations ón the estimation óf the CO 2 stripped show some dependency on the CO 2 loading in the rich amine flux entering the desorber. ![]() Previous article in issue Next article in issue Keywords MEA Post-Combustion Chemical absorption Desorber Modelling Recommended articles Citing articles (0) View Abstract 2017 The Authors.
