1 Scope

GB/T 11060.10-2021 is the Chinese national standard on natural gas - determination of sulfur compounds - part 10: determination of sulfur compounds using gas chromatography method, in the field of petroleum and related technologies. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 11 October 2021 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 May 2022. Classification: ICS 75.060, CCS E24. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the principles, instruments, sampling and injection, calibration, analysis, precision, and measurement of sulfides in natural gas by gas chromatography. testing report. This document is applicable to the measurement of hydrogen sulfide, carbonyl sulfide, C1-C4 alkyl mercaptans, tetrahydrothiophene (THT), sulfur compound content, and total sulfur. Determined, the measurement range. 0.1mg/m3 ~ 600mg/m3.

Note. The different detection methods in the appendix can be selected according to the situation of the sample. With different detection methods, the components and concentrations of sulfur compounds that can be measured will vary different.
