天然气中汞及其化合物的检测系统与分析方法研究

Study on Detection System and Analysis Method of Mercury and Its Compounds in the Natural Gas

准确测定天然气中汞及其化合物的采样方法和分析技术成为近年来一个重要的研究内容。文章对该项技术进行了实验研究,并依据研发的实验装置建立了相应分析方法。实验表明:甲基汞加标回收率为87.5%～92.2%;乙基汞加标回收率为86.5%～92.0%,采用该套检测系统可以对天然气中汞及其化合物进行有效的分离和定量分析。

Sampling method and analysis technique for accurate determination of mercury and its compounds in the natural gas were the scientific research content. An analysis method was set up based on the experimental devices invented. The results of experiment showed that the recovery of methyl mercury and ethyl mercury were 87.5%～92.2% and 86.5%～ 92.0% respectively. The experiment device was effective on separation and quantitative analysis of mercury and its compounds in the natural gas.
