Analysis of the dynamic performance of a MEA-based carbon capture unit for coal-fired power plants by Carsten Trapp and Robert de Kler

In this study the constraints and flexibility during transient operation of a PCC unit are assessed using an equilibrium-based dynamic model of the capture unit. The dynamic models are developed in Modelica, an open-source, object-oriented and equation-based language for the modeling of physical systems. Where possible, existing model libraries are used or modified in order to obtain a complete model of the capture unit. The plant utilizes Monoethanolamine (MEA) as the absorption fluid. The dynamic model is validated with openloop step response tests performed at the TNO pilot plant.
