Standard Test Methods for Traces of Volatile Chlorides in Butane-Butene Mixtures
Standard Test Methods for Traces of Volatile Chlorides in Butane-Butene Mixtures
SIGNIFICANCE AND USE 4.1 These test methods are used to determine trace amounts of volatile chlorides in butane-butene mixtures. Such information is valuable in cases where chloride is deleterious in the use of this product; also, chloride contributes to corrosion problems in processing units in instances where further processing of this material is involved. SCOPE 1.1 These test methods cover the determination of the total volatile organic chlorides in concentrations from 10 mg/kg to 100 mg/kg in butane-butene mixtures. The amperometric finish is not directly applicable in the presence of other substances that combine with silver ion or oxidize chloride ion in dilute acid solution. Bromides, sulfides, ammonia, tobacco smoke, and more than 25 μg of hydrogen peroxide in the test solution interfere in the spectrophotometric procedure. 1.2 Dissolved sodium chloride is not quantitatively determined using these test methods. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific warning statements are given in Sections 5, 8, 11, 14, 19, and Annex A1. 1.4.1 The user is advised to obtain LPG safety training for the safe operation of this test method procedure and related activities. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
ASTM D2384-23: Standard Test Methods for Traces of Volatile Chlorides in Butane-Butene Mixtures is a critical standard developed by ASTM International. It provides laboratory procedures for accurately determining trace amounts of volatile organic chlorides, in concentrations ranging from 10 mg/kg to 100 mg/kg, in butane-butene mixtures. As chlorides in these hydrocarbon streams can lead to significant corrosion in processing equipment and cause detrimental effects on end-use applications, routine trace chloride analysis is essential for quality assurance and plant reliability.
This standard supports organizations in the chemical, petrochemical, and energy sectors in monitoring, reporting, and managing volatile chloride contamination in liquefied petroleum gas (LPG) products such as butane and butene.
ASTM D2384-23 is widely used in sectors where control of volatile chlorides in LPG streams is crucial, including:
