Abstract

Diversification of electricity generation sources and changing consumer demand as well as electricity pricing could hinder the performance of a post combustion capture plant attached to a fossil-fueled power plant. This has necessitated advanced control algorithms to ensure safe, flexible and economical operation of the plant. In this work, economic model predictive control (EMPC) was applied to a post-combustion capture plant. The performance of the EMPC was compared to the one given by a set-point tracking model predictive controller (MPC) in terms of emission reduction and reboiler heat requirements. The results show that EMPC has the potential to improve the economic performance of the process.
