该欧洲标准草案定义了用于确定燃料气体组成的气相色谱分析，如在炼油厂加热气体中使用的那样。这些结果用于计算碳含量和较低的热值。 通过该气相色谱分析，总共23个炼油厂加热气体组分按照炼油厂中通常的浓度确定（详见表1）。 水不分析。结果表示干燥气体。 注1:根据所使用的设备，有可能确定高级碳氢化合物。 注2:为了本欧洲标准草案的目的，术语“％（V/V）”用于表示体积分数（φ）。 重要信息 - 本标准并不旨在解决与其使用相关的所有安全问题。本标准用户有责任建立适当的安全和卫生实践，并确定监管限制的适用性

This draft European Standard defines a gas chromatographic analysis for the determination of the composition of fuel gases, as used in refinery heating gas. These results are used to calculate the carbon content and the lower calorific value. With this gas chromatographic analysis, an overall of 23 refinery heating gas components are determined in concentrations as typically found in refineries (see Table 1 for further details). Water is not analyzed. The results represent dry gases. NOTE 1 Depending on the equipment used, there is a possibility to determine higher hydrocarbons as well. NOTE 2 For the purposes of this draft European Standard, the terms "% (V/V)" is used to represent the volume fraction (φ). IMPORTANT - This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations.
