Abstract:
Post combustion capture via chemical absorption is viewed as the most mature CO
capture technique. The effects of the addition of CO chemical absorption process
on power plant performance have been studied using various steady-state models.
However, there are several gaps in the understanding of the impact of post
combustion capture on the operability of the power plant. These questions could
be addressed by studying the dynamic behavior of such plants. In this study,
dynamic models of the CO chemical absorption process were developed and
validated. Dynamic analyses of the process reveal that absorber performance is
sensitive to L/G ratio and that changes in reboiler duty significantly affect
the regenerator performance.
