GOST 10679-2019 PDF

Full title and description

GOST 10679-2019 — Межгосударственный стандарт: «Газы углеводородные сжиженные. Метод определения углеводородного состава» (English: Liquefied hydrocarbon gases — Method for determination of the hydrocarbon composition). The standard specifies a chromatographic analytical method and related requirements for determining the hydrocarbon composition of liquefied hydrocarbon gases (LHG/LPG) such as propane, propene, butanes and butenes and their mixtures as produced from oil and gas processing.

Abstract

GOST 10679-2019 defines procedures for sampling, chromatographic measurement, calibration, data processing and reporting to determine the mass or molar fractions of paraffinic and olefinic hydrocarbons in liquefied hydrocarbon gases. It includes recommended chromatographic columns, detectors, operating conditions, limits of measurable components and requirements for personnel qualification and safety. The standard updates and replaces the older GOST 10679-76.

General information

• Status: Active — interstate (GOST) standard, adopted by the Interstate Council and implemented as a national standard (introduced 1 January 2020).
• Publication date: 2019 (officially put into effect 01 January 2020).
• Publisher: Interstate standard published under the authority of the Межгосударственный совет по стандартизации, метрологии и сертификации (EASC); implemented in the Russian Federation by the Federal Agency on Technical Regulating and Metrology (Rosstandart).
• ICS / categories: 75.040 (hydrocarbon gases and gas technology / measurement of hydrocarbon composition).
• Edition / version: 2019 edition — replaces ГОСТ 10679-76.
• Number of pages: 36 pages (electronic/print formats reported).

Scope

The standard applies to liquefied hydrocarbon gases obtained from petroleum refining, gas condensate and associated or natural gas streams and sets out a method (primarily gas chromatography) to measure the content of hydrocarbon components (paraffins and olefins) across the specified measurement ranges. It is intended for laboratory analysis used in production control, quality assessment, regulatory compliance and trade.

Key topics and requirements

• Requirements for sampling and sample handling to preserve representative composition and safety.
• Gas chromatographic method details: recommended column types (packed and capillary), column lengths and dimensions, detector options (TCD, FID/PID), carrier gases and flow rates, temperature programs and sample volumes.
• Calibration procedures, use of reference standards, and calculation of mass or molar fractions for target hydrocarbon components.
• Measurement ranges, limits of detection/quantification and performance expectations for typical laboratory equipment.
• Data processing, reporting format and statement of uncertainty; requirements to document conditions of analysis and sample identity.
• Personnel qualification, laboratory conditions and safety measures for handling flammable hydrocarbon gases.

Typical use and users

Primary users include analytical and quality laboratories at refineries, gas-processing plants and petrochemical facilities; independent testing laboratories; foundries and equipment manufacturers that require composition data for LPG feedstocks; regulatory bodies and certifying authorities responsible for fuel quality and trade; and procurement and quality-control engineers. The standard is used for production control, compliance testing, custody transfer verification and research/development of analytical procedures.
