The industrial automation is based on the design and implementation of systems that control material processes and manage decision-making, in order to optimize processes and reduce human efforts. With the advancement of technologies, this automation is expanding more and more and, in parallel, there is a significant growth of risk analysis methodologies in the industries. Concern for worker safety and environmental safety is one of the main factors that contribute to the advancement of these analyses. For the present study, a HAZOP of the continuous reactor used in the manufacture of Sodium Formate was developed, focusing on the analysis of the pressure transient due to the rapid closing of the control valve installed in the pipeline. The risk analysis of this scenario was performed based on the methodology typically used in HAZOP. The results obtained in the calculations performed show that there would be a sudden increase in pressure in the reactor supply line, upstream of the control valve, and that this increase would not put the piping at risk due to the aforementioned deviation.
