Abstract: “Development of dynamic models for post-combustion CO2 capture using monoethanolamine solvent has been reported in the literature. Such models are only validated at steady-state, which means the models can predict process performance at different operating points. However, without dynamic validation, there is no guarantee that the model in question would predict dynamic responses accurately. This paper presents a dynamic validation study. …”
Comments: the authors are using gPROMS from Process Systems Enterprise to model the amine plant and are using the Electrolyte Non-Random-Two-Liquid (ElecNRTL) model, an activity coefficient model available in Aspen Properties®, to describe the vapour–liquid equilibrium, the chemical equilibrium and the physical properties of the system. gPROMS accesses Aspen Properties through the link provided by the implementation of the CAPE-OPEN Thermodynamic and Physical Properties interface specification on both sides.
