In this paper, adaptive Kalman filter (KF) algorithms are implemented in an acid gas removal (AGR) process for estimating the key environmental performance variables. It was found that by using a KF where the measurement noise covariance matrix (R) is adopted based on the residual sequence, the composition of the top and bottom streams from the H2S absorber in the AGR process could be estimated accurately...
This work is focused on the development of a rigorous, model based approach for the selection of primary controlled variables as part of a plant-wide control system design methodology. Selected controlled variables should exhibit good self-optimizing control performance while not sacrificing controllability. The approach developed in this work for the controlled variable selection problem results...
