3 Classification and quality requirements

3.1

Natural gas is classified into one type and two types according to high calorific value, total sulfur, hydrogen sulfide and carbon dioxide.

3.2

The quality requirements for natural gas should meet the requirements of Table 1.

3.3

For the quality requirements of sulfur content in natural gas in some countries and regions in Europe and America, see Appendix A.

Table 1 Natural gas quality requirements

Project class II High calorific value a, b/(MJ/m3) >= 34.0 31.4

Total sulfur (in terms of sulfur) a/(mg/m3) <= 20 100

Hydrogen sulfide a/(mg/m3) <= 6 20

Carbon dioxide mole fraction /% <= 3.0 4.0 a The standard reference conditions used in this standard are 101.325 kPa, 20 °C.

b High calorific value is measured on a dry basis.
