摘要
呼图壁储气库作为全国已建最大的储气库,在天然气外输计量中,计量安全性、稳定性及精确度显得尤为重要,呼图壁储气库结合新疆地区特有的环境条件,设计了分析小屋,分析小屋内置水露点分析仪、烃露点分析仪、色谱分析仪等设施。使用水、烃露点分析仪,降低了天然气在集输管道中凝水、凝液的风险,提高安全性;应用色谱分析仪,分析天然气组分,计算出实时动态补偿气体压缩因子,提高了天然气外输计量的精度;使用分析小屋,为分析仪表提供了稳定、适宜的工作环境。因此,掌握外输分析仪表的原理和使用注意事项,合理进行操作与维护,从而满足天然气外输计量要求。
The gas storage built in Hutubi is the biggest gas storage in China, in the transmission measurement of natural gas, it is very important for security, stability and accuracy of the measurement, based on the specific environmental conditions in Xinjiang, the analysis cabin has been designed where has water dew point analyzer, hydrocarbon dew point analyzer and chromatographic analyzer. By using the water dew point analyzer and hydrocarbon dew point analyzer, it reduces the risk of condensate in the gas pipeline. By using the chromatographic analyzer, it analysis the composition of natural gas and calculate the real-time dynamic compensation factor to improve the accuracy of gas transmission measurement. By using the analysis cabin, it provides a stable and suitable working environment for the analysis instrument. Therefore, it is necessary to master the principle and attention of the analysis instrument and operate and maintain reasonably to satisfy the requirement of the transmission measurement of natural gas.
