摘要
随着我国煤层气工业的快速发展,大部分煤层气都将通过管线进行输送,因此对煤层气气质指标研究显得十分重要。本文参考天然气发热量的计算方法,利用各组分压缩因子、求和因子和摩尔发热量的数值,对我国晋城地区的煤层气发热量进行了计算。计算结果表明:我国煤层气的高、低位发热量值能达到天然气管输送标准的指标要求。但与国外部分地区相比,我国煤层气的发热量值偏低。
With the rapid development of coalbed methane （CBM） industry in China, most of the CBM will be transmitted by pipelines, so research on the quality index of CBM becomes important. This paper calculates the CBM thermal value in China, by referring to the calculation ＇of thermal value of natural gas and using the figures of the compressibility factors, summation factors and mol thermal value of different components. The results show that the hi - lo thermal value of CBM in China can attain the standard of pipeline transmitting, but compared with other countries, the CBM thermal value is relatively lower.
