Resumen
[EN]Absorption carbon capture is currently the most commercialized technology and deemed as the vital solution to
balance continued use of fossil fuels and carbon emission reduction. Nevertheless, its high energy cost remains
the major concern for wide-scale application. Consequently, it is of great significance to address this issue by
analyzing the underlying energy conversion mechanism, answering the pivotal question “What characteristics
lead to a superior absorbent?”, and developing more efficient absorbent. In this paper, an irreversible decoupling
model of absorption carbon capture system, consisting of a heat engine and a chemical pump, is innovatively
established. Accordingly, key performance indicators are analytically derived and the optimal operation strategies
of the system are explicitly determined. Notably, the matching of two subsystems leads to a novel insight
into the heat and mass transfer interaction of absorbent, according to which the simulated results and the
question concerning the best absorbent are thermodynamically interpreted and addressed, respectively. Additionally,
the comparisons between the calculated optimal energy conversion efficiencies with experimental and
simulated results are presented and discussed. Our findings may indicate the efficient pathway for developing
advanced absorbent and provide instructing information for the design and operation of practical carbon capture
systems.
