Nonlinear Model Predictive Control of a CO2 Post-Combustion Absorption Unit

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift

Abstract

A dynamic model of a chemical CO2 absorption process with aqueous monoethanolamine (MEA) is presented, validated against experimental data. Based on the validated model, a reduced-order model is developed, suitable for an online optimization control strategy. The objective of the optimization is to enable fast adap- tations to changes in operating conditions of the power plant, while minimizing the energy consumption in the operation of the CO2 separation plant. The results indicate that model-based online optimization is a feasible technology for control of CO2 separation systems.
