DETERMINATION OF PARAMETERS IN LINEAR CHE MICAL PROCESSES

The authors describe a straightforward and extremely reliable method f or determination of the physicochemical parameters occurring in mathem atical models of chemical processes. It is based on the restrictive as sumption that the system considered is linear and the number of parame ters is small. These assumptions permit a detailed eigenvalue analysis of the system, permitting a complete insight into its behaviour. The eigenvalues lambda(k) and the factors a(k) of the corresponding expone ntial functions are determined by curve fitting. These in turn are det ermined by system parameters and thus afford relations from which the latter can be calculated. Use of the proposed model requires the desig n of experiments which can be described by approximately linear models . This is indeed possible in many cases.
