ABSTRACT
The carbonation process of Solvays soda plant is essentially a Multi-Input-Multi-Output (MIMO) system with strong coupling among process variables, severe disturbance and process nonlinearity. Classical control structure with multi-loop PID control usually cannot maintain a long-time stable control in the practical process. This study introduces industrial application via a commercial software of MPC for three blocks of carbonation towers in a soda plant which consists of fifteen carbonation towers, A MPC system constructed of controlled variables, manipulated variables and disturbance variables, was developed to deal with the constrained multivariable control problem on-line of the carbonation towers. Industrial application results have shown that the MPC software can maintain the best operation for a long time and realize ultimate operating potential of the carbonation systems by reducing the consumption of material, improving product quality and minimizing operating cost.
