Standard Test Method for Total Fluorine, Chlorine, and Sulfur in Liquid Petroleum Gas (LPG) by Oxidative Pyrohydrolytic Combustion Followed by Ion Chromatography Detection (Combustion Ion Chromatography-CIC)

Importancia y uso:

5.1 The total fluorine, chlorine, and sulfur contained in LPG, similar low molecular weight hydrocarbons, and DME can be harmful to many catalytic chemical processes, lead to corrosion, and contribute to pollutant emissions. While LPG specifications limit sulfur, some specifications also contain precautionary statements about fluorine. Chlorine has been known to contaminate LPG with detrimental consequences. This test method can be used to determine total fluorine (as fluoride), chlorine (as chloride), and sulfur (as sulfate ion) in process streams, intermediate and finished LPG products, similar low molecular weight hydrocarbons, and DME (1.1).
