The model structure is a combination of first principles with standard black-box techniques. The approach is based on easily established mass balance equations, the stoichiometry of the system and a model reduction from fast system dynamics. This model makes use of a combined physically meaningful variable from several physical inputs of the process. It is also a key variable for the optimization and the control of the underlying process. This model structure has been successfully used in an IMC scheme for the on-line control of this process.
