GC2020 天然气热值检测仪


GC-2020天然气热值检测仪价格、天然气热值分析仪原理及使用说明由滕州中科谱分析仪器有限公司提供
【产品原理】天然气是由多种组分构成的混合物。天然气的组成是指天然气中所含的组分及其在可检测范围内的相应含量。在检测时通常所指的组成是指天然气中甲烷、乙烷等烃类组分和N2、CO2等常见的非烃组分的含量。尽管天然气还含有如硫化物、水等杂质,但如果不特别说明,在组成分析时并不检测这些组分。在商品天然气的组分分析中,由于组分相对稳定,只要求对Cl至C6的烃类组分进行简单分析(也称常规分析)。
目前,我国针对天然气组分分析的气相色谱法,制定的国家推荐标准《GB/T13610一2003天然气的组成分析一气相色谱法》采用外标法,检测器使用热导检测器(TCD)和氢火焰离子检测器(FID)。
滕州中科谱分析仪器有限公司生产的GC2020天然气热值检测仪配置采用叁柱并联一次进样实现天然气中八种组分(甲烷、乙烷、丙烷、异丁烷、正丁烷 &nbs; 异戊烷、正戊烷 、二氧化碳、氧气、氮气)分析,并通过热值版色谱工作站根据组分来计算其密度,压缩因子,发热量等。
天然气热值检测仪配置】

【技术优势】
1、仪器即可用于天然气、液化气混空的组成分析,还可以用其氢气,氮气,甲烷为原料气配比的各种燃气组分分析。
2、仪器在一次样品分析完后可通过特有的自定义报表报出被测气组成含量、高热值、低热值等特性指数。
3、仪器适用于:LNG加气站,LNG气化站,城市燃气储备站,门站等一切需要测试天然气中成分的场合!
