Análisis de la Sensibilidad Paramétrica de la Síntesis de o-Nitroanilina en un Reactor Batch Industrial

Abstract

In this work, the parametric sensitivity of the production process of o-nitroaniline, from ammonia and o-nitrobenzene, was studied with the aim of determining its safe operating conditions. The industrial batch operation data, related to the accident occurred at the Monsanto plant located in Sauget, Illinois, United States, were analyzed. For the conditions of that day, using the mass and energy balances, the variation of the reactor temperature was modeled. Additionally, local-sensitivity temperature coefficients were calculated with respect to the amount of o-nitrobenzene fed to the reactor for different initial operating temperatures. Thus, safe operating conditions were determined according to different initial operating conditions. Finally, it was explained how the combination of two factors in the operational conditions (reactor load and failure in the service fluid) were the factors that promoted the rupture of the reactor.
