Chlorides in crude contribute to corrosion damage in blending operations, pipelines, or refining processes. Organic chlorides do not naturally occur; however, inorganic chlorides in the form of salts and trace levels of residual organic chlorides from natural sources can contribute to the total chlorine content. After desalting, low levels of organic chlorides may remain. The need for a reliable measurement of low-level and trace chlorine is critical.

NEX CG II gives superior performance for measuring organic chloride in crude oil per ASTM D4929 Part C. It also allows users to measure and monitor sulfur, metals, and other elements and meet compliance with multiple testing methods and standards.
