Modeling post-combustion CO2 capture with amine solvents

Carbon capture and storage is a technology that can contribute to face the challenge of
rising energy demand combined with a growing environmental awareness. In the
present work, the CO2 capture process with monoethanolamine (MEA) is modeled using
the simulation tool Aspen Plus. Two different modeling approaches are studied and
compared: the equilibrium and the rate-based approaches. An optimization of key
process parameters is performed and process modifications are studied with the
objective of improving the global process energy efficiency.
