标准摘要
[中文适用范围]： 规定：在基准条件下，基于组成成分计算天然气混合物的以下特性：高热值、相对密度（真实值与理想值）、压缩因子及理论碳氢化合物液体含量（在美国通常以“加仑/千立方英尺”（GPM）表示）。水对这些计算的影响进行严格计算颇为复杂。鉴于本文件主要用于计量交接，其中关于水影响的计算采用可接受的合同计算方法。本标准的附录A详细研究了水的影响，并推导了标准中所列公式的详细过程。 [外文原描述]： Presents procedures for calculating, at base conditions from composition, the following properties of natural gas mixtures: gross heating value, relative density (real and ideal), compressibility factor and theorectical hydrocarbon liquid content which in the U.S. is typically expressed as GPM, the abbreviation for gallons of liquid per thousand cubic feet of gas. Rigorous calculation of the effect of water upon these calculations is complicated. Because this document relates primarily to custody transfer, the water effect included is an acceptable contractual calculation. Annex A of this standard contains a detailed investigation of the effect of water and detailed derivations of the equations presented in the standard.
