Avaliação da área classificada aplicada à produção de acetileno

Abstract

Classified areas are areas in which an explosive atmosphere is present or may be present, in such a quantity as to require special precautions, for the installation and use of equipment. Considering a common chemical industry installation scenario, a HAZOP was drawn up for the acetylene production generator, with a focus on mapping and defining the areas around the generator that could pose a risk of explosion due to the presence of an explosive atmosphere during the manufacture of acetylene. The risk analysis was based on the methodology used in HAZOP. The results obtained in the studies show the points on the equipment where there could be a risk of explosion, along with the causes and consequences. He was also able to estimate and quantify the volume of the areas around the points that could pose a risk of explosion due to the presence of flammable gases.
