摘要：

Dynamic modelling for post-combustion CO2 capture using monoethanolamine (MEA) solvent has been validated at steady state in the past. This paper presents a dynamic validation. The absorber and regenerator were modelled using the two-film theory in gPROMS (R). Electrolyte NRTL model in Aspen Properties (R) is used to describe the chemical equilibrium and vapour-liquid equilibrium. The CO2 capture process was simulated. The temperature profile of the absorber, the capture level and the regenerator duty were compared with pilot plant data logs. It is observed that the model satisfactorily predicts the behaviour of the pilot plant due to a number of process inputs and disturbances, producing trends in close agreement with the data logs.
