In this paper, the Real Time Evolution technique (RTE) is applied to the on-line optimization of a multi-component distillation column. A Fault Diagnosis System (FDS) implemented within a supervisory module is responsible for handling incidences (faults or disturbances) occurring in the plant, achieving more robust on-line performance. The implementation of the supervised scheme (SRTE) has been performed using Matlab® and the commercial simulation software Hysys®, taking advantage of their communication capabilities. Different possible plant incidences are considered involving different sources and types of disturbances. Results of SRTE are compared with those obtained using the standard Real Time Optimization approach.
