Model predictive control of post-combustion CO<inf>2</inf> capture system for coal-fired power plants

Model Analysis for the Implementation of a Fast Model Predictive Control Scheme on the Absorption/Stripping CO2 Capture Plants

“…A theoretical stripper has been added to this plant for the complete design of the absorption/stripping system. This theoretical stripper is designed based on the conventional design, as described in the literature. − The adequate contact area for CO 2 gas and MEA solvent inside the column is provided by structured or random packing. MacDowell et al proposed that the most promising option for carbon capture is structured packing because of its economical accessibility, large contact area, and low pressure drop.…”

“…Using the developed Aspen Dynamics model designed in Section , the corresponding input–output data are generated by utilizing pseudorandom binary sequence (PRBS) signals by fixing the ±5% amplitude with respect to the datum point with a period of 30 min for U 1 and U 2 . The design of the PRBS signals is a critical step that gathers the critical characteristics of the CO 2 capture plant by considering the plant outputs based on input changes …”
