UOP 588 – Total, Inorganic, and Organic Chloride in Hydrocarbons
This potentiometric method is for determining total and inorganic chloride, and calculating organic chloride, in hydrocarbons. The method is applicable to samples with chloride concentrations of 1 mass-ppm or higher. For lower levels of chloride use UOP Method 991 Chloride, Fluoride, and Bromide in Liquid Organics by Combustion Ion Chromatography (CIC). Iodide and/or bromide, if present, are calculated as chloride. Samples that are polymerized by sodium biphenyl (such as styrene) cannot be analyzed by this method. Results for samples containing ammonia and/or amines may be biased high (see Note 1).
