基于西门子SITRANS CV在线色谱分析仪的热值计量系统设计与应用

Design and application of calorific value measurement system based on SIEMENS SITRANS CV online chromatography analyzer

近年来国家颁布了一系列标准,规定逐步采用能量计量方式替代体积(或质量)计量方式进行贸易结算,贸易结算更趋科学、合理。本论文基于西门子SITRANS CV在线色谱分析仪设计了热值计量系统,包括样品处理系统、各种辅助配套设备及软硬件系统,实现了天然气热值测量的自动化、智能化和标准化。

In recent years, the state has promulgated a series of standards, which stipulates that energy metering shall be adopted gradually instead of volume（or quality） for settlement of trade, and trade settlement will be more scientific and reasonable？ The SIEMENS SITRANS CV online chromatographic analyzer is designed based on the calorific value measurement system, including sample processing system, all kinds of auxiliary equipment and hardware and software system, realizes the automation, intelligent and standard measurement of the calorific value of natural gas？
