标准范围

ISO 12213规定了在混合物只能作为气体存在的条件下计算天然气、含有合成混合物的天然气和类似混合物的压缩因子的方法。它分为三个部分:这一部分ISO 12213-2:20 06规定了当已知气体的详细摩尔分数组成以及相关压力和温度时计算压缩因子的方法。该方法适用于通常进行输配操作的压力p和温度T范围内的管道质量气体，不确定度约为+/-0.1%。它可以以更大的不确定性应用于更宽范围的气体成分、压力和温度。

ISO 12213 specifies methods for the calculation of compression factors of natural gases, natural gases containing a synthetic admixture and similar mixtures at conditions under which the mixture can exist only as a gas.It is divided into three parts: this part, ISO 12213-2:2006, specifies a method for the calculation of compression factors when the detailed composition of the gas by mole fractions is known, together with the relevant pressures and temperatures.The method is applicable to pipeline quality gases within the ranges of pressure p and temperature T at which transmission and distribution operations normally take place, with an uncertainty of about +/- 0,1 %. It can be applied, with greater uncertainty, to wider ranges of gas composition, pressure and temperature.
