Salinidade em petróleo bruto: otimização de metodologia e proposta de um novo método para extração de sais em petróleo Salinity of crude oil: optimization of methodology and new method for extraction of salt in petroleum

Abstract

The quantity of salts in the crude oils depends on the origin and of the wells production and these salts cause several problems during the transport and the process of refine as corrosions, incrustations and deactivation of the employed catalysts in the refineries. In this study were implemented changes for improvements in the execution of ASTM D 6470 method and has also developed a new methodology of extraction system of salts using process of mechanical agitation without heating. The results of the optimization produce larger efficiency and safety to the process compared to the traditional ASTM method.
