Controllability and flexibility analysis of CO 2 post-combustion capture using piperazine and MEA

Effects of CO2-Absorption Control Strategies on the Dynamic Performance of a Supercritical Pulverized-Coal-Fired Power Plant

“…In the proposed scheme, the mass flow of steam (ṁsteam) is used to control the CO2 removal rate, and the solvent circulation rate downstream of the absorber is manipulated to maintain a set temperature at a specific stage in the stripper. The same control scheme was presented by Gaspar, et al 10 based on a Relative Gain Array analysis, though a subsequent sensitivity analysis suggested opposite pairing of control and manipulated variables. Nittaya, et al 11 have presented a controllability study of an MEA-based absorption unit, in which they have developed three decentralized control schemes for an MEA-based absorption process with a simple absorber-stripper setup and evaluated the performances of the schemes in several scenarios, including a change in the flue gas flow rate, a change in the CO2-capture rate, and a valve stiction.…”

Recent advances on first-principles modeling for the design of materials in CO2 capture technologies

“…allotropes of carbon such as nanotubes or graphenes allow the specific applications of porous carbons. Mo et al [37] [42], [43], [158], [159], [160], [161], [162]. Yamada et al [48] developed a continuum ACCEPTED MANUSCRIPT…”

Robust optimization of a post-combustion CO2 capture absorber column under process uncertainty

“…Moreover, model development has advanced the study of optimal design and operations management policies for post-combustion systems. In most of those works, single-objective design optimization has been considered (Chu et al, 2016;Gaspar and Loldrup, 2016;Mores et al, 2012Mores et al, , 2018Thouchprasitchai et al, 2018). Furthermore, efforts to establish a more flexible though efficient CO2 capture process have been addressed through the formulation of multi-objective optimization problems (Bernier et al, 2010;Cristóbal et al, 2012;Eslick and Miller, 2011;Fazlollahi and Maréchal, 2013;Haghpanah et al, 2013;Harkin et al, 2012;Li et al, 2006) .…”
