The development of amine scrubbing processes for coal and natural gas-fired power plants is essential to reduce CO2 emissions. The design of tailor-made dynamic models to predict CO2 capture in amine scrubbing processes is fundamental for optimal control operations. This paper presents the use of SIMPCA, a subspace system identification technique used to develop a dynamic empirical model for an LQG controller with integral action. Such a controller is made to attain optimal operating conditions for a CO2 capture pilot plant. Reference signals are used in conjunction with the controller integral action to bring few process outputs towards their set-points. The results illustrate the importance of reliable model prediction in order to provide desirable closed loop response and appropriate CO2 emission reduction. © 2011 IEEE.
