✦ Synopsis

An optimal steady-state sequential distributed filter has been derived and tested. A iimitedmemory type modification is presented and shown to have superior convergence properties compared to the optimal filter when a number of replicate data sets are available for processing. Experimental data from a styrene-monomer tubular-reactor pilot plant were processed using the modified filter since replicate sets of data were available. Results show steady-state sequential filtering to be effective and robust.

A simple and efficient on-line scheme is developed to estimate temperature and compositions along a packed bed reactor in which styrene is being produced by the dehydrogenation of ethylbenzene. Slowly varying catalyst activity is also identified. The system is distributed in time and axial position
