标准摘要
[中文适用范围]: 本文件的目的是为用户提供推荐的“现场”采样、样品处理和分析方法,用于按体积计算含水量高达 50% 的高含水量流。特别是,该RP的制定考虑了海上设施(浮动平台和固定平台)。这些装置通常会受到运动和振动@具有最少的实验室设备@并由多技能操作人员而不是实验室化学家执行软件分析。然而,所描述的技术@也适用于陆上地点。本文件提供了高含水量流@体积含水量高达 50% 的采样@样品处理和样品分析的设计和操作指南。作为指导@,该 RP 的目标是读取最高 50% 水含量的相对精度为 5%,作为本文所述各种方法的限定符。例如,@ 10% 含水量流的相应绝对精度为 ?? 0.5% 和 20% 的含水量是 ?? 1.0%。本建议的做法可能涉及危险材料@操作@和设备。本 RP 并不旨在解决与其使用相关的所有安全问题。本 RP 的用户有责任在使用前建立适当的安全和健康实践并确定监管限制的适用性。本 RP 中包含的实验室测试(参见附件 A)基于单个实验室——单个操作员的一组结果。与现场 SW 测定方法的其他 API 标准一样,没有进行精度和偏差计算,因此没有进行实验室间或循环式测试。各种方法的测试结果主要是为了提供不同方法之间的一般比较,以方便操作选择。 [外文原描述]: Provides the user with recommended ‘field’ methods of sampling, sample handling and analysis for high water content streams up to 50 % water on a volumetric basis. In particular, this RP was developed giving consideration to offshore installations (both floating and fixed platforms). These installations are generally subject to motion and vibrations, have minimal laboratory equipment and perform S&W analysis with multi-skilled operations personnel as opposed to laboratory chemists. The techniques described, however, are applicable to onshore locations. Provides design and operating guidelines for sampling, sample handling and analysis for high water content streams, up to 50 % water on a volumetric basis. As a guide, this RP targets a relative accuracy of 5 % of reading up to a maximum of 50 % water content as a qualifier for various methods described herein. For example, the corresponding absolute accuracy for a 10 % water content stream is ± 0.5 % and for 20 % water content is ± 1.0
