天然气压缩因子影响因素的研究

Research on Impacting Factors of Natural Gas Compressibility Factor

天然气长输管道首端与末端之间往往会出现输差,输差是影响输气成本的一个最关键的因素。寻找出输差的各种因素,调研发现影响输差的主要元素是天然气压缩因子,以天然气组分为基础,通过对天然气压缩因子的调研,得到影响压缩因子的主要因素,提出一定的建议改进从而修正到天然气输量,以便减少输差。

There is always measurement shortage between the head-end and the terminal of long-distance gas transmission pipelines, and the measurement shortage is one of the most critical factors affecting gas cost. In this paper, various factors to cause the measurement shortage were investigated,it＇s pointed out that the main factor affecting the measurement shortage is natural gas compressibility factor. The natural gas compressibility factor was analyzed and studied, main factors influencing the compressibility factor were obtained. Finally some suggestions about modifying the gas throughput were put forward, in order to reduce the measurement shortage.
