摘要 因硫化氢有毒有害的特性,在工业生产过程中需对其浓度进行检测。介绍了可调谐二极管激光吸收光谱技术(TDLAS)气体分析系统工作原理及系统组成,以监测天然气脱硫过程中的硫化氢浓度为应用案例,采用基于TDLAS的分析系统进行浓度分析。通过模拟天然气应用场景产生的硫化氢混合气体,采用化学计量学方法计算硫化氢浓度,结果显示该分析系统满足当前石化行业对痕量气体的测量需求,且具有非接触式、反应迅速、测量精确等优点。 Because of hydrogen sulfide is toxic and harmful, It is of great significance to detect the concentration of hydrogen sulfide in industrial production. The working principle and system composition of tunable diode laser absorption spectroscopy(TDLAS) gas analysis system is introduced. Taking monitoring concentration of hydrogen sulfide in the process of natural gas desulfurization as an application example, the analysis system based on TDLAS technology is used for concentration measurement. Hydrogen sulfide mixture is produced by simulating natural gas application scenarios, and the hydrogen sulfide concentration is calculated by the chemometric method. The results show that the analysis system meets the needs of trace gas measurement in petrochemical industry and has the advantages of non-contact, rapid reaction and accurate measurement.
