摘要
天然气计量直接关系到天然气贸易的公平性,文中针对天然气计量过程中的计量误差问题,进行了多种计量方式的对比。结果表明,我国普遍采用的体积计量方式,由于仪表问题、气质问题、使用条件问题以及管道内壁粗糙度等原因,使得计量过程经常产生较大误差,有必要在我国推行能量计量方法。
Natural gas metering is be directly related to the fairness of natural gas trade.Therefore,research on natural gas metering technology is very important.In view of the error in the natural gas measurement process,the most common measurement methods are introduced and analyzed,and the measurement methods are compared in multiple directions.The causes of errors in the natural gas measurement process are analyzed in depth.According to the actual situation in China,the adoption of natural gas in China is proposed.The necessity of energy measurement methods lays the foundation for ensuring the fairness of natural gas trade.Research shows that the current common measurement methods include volume measurement,mass measurement and energy measurement.The volume measurement method is widely used in China,but due to the problems of instrumentation,temperament,use conditions and roughness of the inner wall of the pipe,the measurement is made.The process is prone to errors.In order to promote trade fairness and promote the development of China's natural gas international trade,it is necessary to implement energy measurement methods in China.
