Development of method for monitoring of chloride release in the oil refining processes

During oil refining, equipments are constantly exposed to the action of compounds such as salts, leading corrosion problems and to decrease in equipment service life. Soon, the growing search for productivity increasingly demand more strategies to monitor the processes and minimize costs. This article contributes to the methodology development to study the chlorides released during the oil distillation, in a similar process that occurs in refineries, enabling predict and minimize damage. Oils were evaluated with respect to chloride release during each stage of oil heating. Salinity mass balance were obtained as well as their respective chloride release percentage to each oil.
