OJEDA TORO, Juan Carlos; DOBROSZ GOMEZ, Izabela  e  GOMEZ GARCIA, Miguel Ángel. PARAMETRIC SENSITIVITY ASSESSMENT OF THE CYCLONITE PRODUCTION IN A BATCH REACTOR. Rev.EIA.Esc.Ing.Antioq [online]. 2014, n.21, pp.123-132. ISSN 1794-1237.

In the present work, the parametric sensitivity of the cyclonite production in a batch reactor was assessed. The objective was to establish safe operation conditions for this highly exothermic reaction. The reaction rate law was fitted using experimental data published in the literature. Mass and energy balances were reparametrized. Thus, reaction temperature sensitivity criteria were established as a function of initial reaction and cooling temperatures. Critical reaction conditions were defined using the temperature-sensitivity, temperature-conversion, and the locus of the temperature maxima. A critical heat generation potential (M) equal to 34 was defined together with the following runaway critical conditions: a Semenov number (ψ) equal to 0.684, a heat of reaction parameter (B) equal to 15 and an Arrhenius-type number (γ) of 20. Therefore, temperature-conversion profiles precise a critical relation between the cooling and heat potential (N/M) of 2.5786.
