Summary
This application note details the online determination of salt content in crude oil using the ADI 2045TI Ex proof Analyzer from Metrohm Process Analytics. Crude oil, being a complex mixture, contains various impurities, including inorganic salts, which can lead to corrosion in refining units and negatively impact catalysts. The document outlines the necessity for continuous monitoring of salt levels to enhance process control and reduce costs associated with desalting. It describes the desalting process, which typically involves chemical and electrostatic separation methods, and emphasizes the advantages of online analysis over traditional laboratory methods. The ADI 2045TI Ex proof Analyzer is designed for hazardous environments and complies with ATEX directives, ensuring safety and efficiency in monitoring chloride levels in crude oil. The application note also references relevant ASTM standards for salt analysis, highlighting the importance of maintaining low chloride concentrations to prevent downstream corrosion and improve process efficiency.
