Análise de risco de reator empregado na fabricação de formiato de sódio

Abstract

In this work the HAZOP of the continuous reactor used in the production of Sodium Formate was elaborated, considering two scenarios typically found in chemical industrial installations. The focus of the work was on the analysis of the temperature of the reaction mass considering two different deviations applied to different process variables. The first deviation was caused by a failure in the open condition of the control valve installed in the saturated steam pipe used for the initial heating of the reactor and the second deviation was caused by a failure in the closed condition of the control valve installed in the cooling water pipe used during normal reactor operation. The results obtained in the calculations performed indicate that there would be a tendency to vaporize the reactor contents due to the mentioned deviations.
