Methodology of on-line optimisation applied to a chemical reactor

The structure of an on-line optimisation procedure is complex, and may involve several steps from different areas. In this paper, a methodology of on-line optimisation that consists of: steady-state detection, data reconciliation, gross error detection, parameter estimation and optimisation is discussed, and applied under simulation, on a two continuous stirred tank reactor (CSTR) connected in series system. Simulation results show that there are some advantages to be gained when this methodology is applied in conjunction with the ISOPE algorithm.
