UOP 910 Standard Test Method for Determination of Chloride in LPG and Gaseous Hydrocarbons by Oxidative Combustion with Microcoulometric Detection

The UOP 910 standard outlines the test method for determining total chloride in liquefied petroleum gas (LPG) and gaseous hydrocarbons using oxidative combustion followed by microcoulometric detection. This method is applicable to samples with chloride concentrations ranging from approximately 1 to 1000 ng/mL for gases or mass-ppm (µg/g) for LPG. The method measures total chloride, including organic and inorganic chloride. Other halogens present in the sample are calculated as chloride.

Total chloride measurements in LPG and gaseous hydrocarbons are crucial because chloride compounds can cause serious corrosion and fouling in refining and petrochemical processes, leading to equipment damage and operational inefficiencies. Accurately measuring this parameter helps to assess the potential risks during further processing, transportation and storage.

Oxidative combustion ensures the complete conversion of chloride-containing compounds to chloride ions, which are then detected using microcoulometric titration. This detection technique is highly sensitive and provides accurate and consistent results. This makes it particularly valuable for industries requiring high-purity hydrocarbons, such as production of polymers.

In summary, UOP 910 is a crucial standard for determining the total chloride in LPG and gaseous hydrocarbons at levels as low as 1 ng/L Cl.

With the multi EA 5100, Analytik Jena offers a powerful system for total chlorine determination in organic solids, liquids and gases. It´s convenient coulometric detection in combination with integrated safety features, such as self check system, auto protection and heated transfer lines, ensure that low detection limits, as required by UOP 910, can be reached easily.
