This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB 17820-2012 "Natural Gas". The main technical changes of this standard compared with GB 17820-2012 are as follows. ---Modified the quality indicators of a class of gas and two types of gas calorific, total sulfur, hydrogen sulfide and carbon dioxide, into the natural gas of long-distance pipelines The high calorific value was changed from 31.4MJ/m3 to 34.0MJ/m3, and the total sulfur was changed from.200mg/m3 to 20mg/m3, hydrogen sulfide. Modified from 20mg/m3 to 6mg/m3 (see Table 1); --- Removed the technical indicators of water dew point, in the "5 transport and use", increased the "pressure and temperature conditions at the natural gas junction The expression of liquid water and liquid hydrocarbons should not exist in natural gas (see 5.1); --- Increased natural gas test methods GB/T 11060.2, GB/T 11060.5, GB/T 11060.8, GB/T 11060.10, GB/T 27894 (all parts), and the arbitration method for the total sulfur content in natural gas is changed from GB/T 11060.4 to GB/T 11060.8 (see 4.2); --- Added normative references GB/T 30490, GB /Z 33440 and GB 50494, deleted GB 50028; --- Added an informative appendix "Quality requirements for sulfur content in natural gas in some countries and regions in Europe and America" (see Appendix A); --- Removed the.2012 edition of the informative Appendix A and Appendix B on hydrocarbon dew point and gas interchangeability. This standard is under the jurisdiction of the National Energy Administration. This standard was drafted.
