冷藏碳氢液体 静态测量 计算程序

[中文适用范围]： 本文件规定了将测量时条件下的液化石油气（LPG）和液化天然气（LNG）体积转换为标准条件（即15°C和101,325 kPa绝对压力）下相应液态或气态体积，或相应质量或能量（热值）的计算方法。本文件适用于在静态储存条件下，储存在或从储罐中转移并测量的制冷烃类液体的数量。本文件不涵盖加压气体的计算。 [外文原描述]： This document specifies the calculation procedure for converting the volume of liquefied petroleum gas (LPG) and liquefied natural gas (LNG) under the conditions at the time of measurement to the equivalent volume of liquid or vapour at the standard condition (i.e. 15 °C and 101,325 kPa absolute), or to the equivalent mass or energy (calorific content). This document applies to the quantities of refrigerated hydrocarbon liquids that are stored in or transferred to or from tanks and measured under static storage conditions. This document does not cover the calculation of pressurized gases.
