Inf. tecnol. [online]. 2018, vol.29, n.4, pp.83-96. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642018000400083.

A numerical method for the analysis of the behavior of two dynamic systems with multiple stationary states is presented. Two reactive chemical systems of industrial interest were studied: the isocyanate hydrolysis and the acetic anhydride hydrolysis. The simulation was implemented in the Matlab® software using cell-mapping. Stability and multiple steady states were identified for the two cases studied. Finally, it was demonstrated that cell mapping methodology allowed a much faster evaluation of reactor feed conditions. It was found that in some cases it can be up to nine times faster than the conventional method of flow patterns.

Palabras clave : hysteresis; cell-mapping; completed stirred tank reactor; methyl isocyanate hydrolysis; acetic anhydride hydrolysis.
