• W3186809666 abstract "• An MPC controller is applied to the syngas purification by pressure swing adsorption. • The proposed Economic MPC (EMPC) makes use of a Deep Neural Network (DNN) model. • The EMPC control law is solved by a modified Particle Swarm Optimization technique. • The plant-model mismatch is evaluated by phenomenological and DNN surrogate models. • CO2 recovery and purity and H2/CO are controlled while productivity is maximized. A novel Artificial Intelligence-oriented Economic nonlinear model predictive control (EMPC) strategy is proposed herein. It was applied to a Pressure Swing Adsorption (PSA) unit where syngas is purified by porous amino-functionalized titanium terephthalate MIL-125. This study addresses the open research problem of simultaneous economic optimization and advanced control in PSA units. A surrogate model based on a Deep Learning Neural Network (DNN) architecture is built to capture the process dynamics with high fidelity. The deployment of these DNN models into the EMPC control law allows obtaining solutions at a low computational cost, making it feasible to be applied in practice, even if using a particle swarm optimization technique. The robustness of the proposed EMPC controller is evaluated under a realistic plant-model mismatch in a software-in-the-loop approach. An experimentally validated phenomenological nonlinear model of the PSA unit for syngas purification was used to represent the plant and to train the DNN models. While EMPC maximizes the unit productivity in all zone/output tracking scenarios for CO 2 recovery and CO 2 purity, it can successfully fulfill the key operating endpoint constraint related to the H 2 /CO ratio, including the unmeasured perturbation scenarios." @default.
