Abstract
Hydrogen Sulfide, with the character of erosion and strong toxicity, is a kind of associated gas of nature gas. How to measure and monitor the hydrogen sulfide concentration becomes an important issue to be solved in nature gas transfer-process. Online measurement for the hydrogen sulfide concentration before the desulphurization remains very difficult in Bonan gas gathering station of SINOPEC Shengli Oil Field (SOF).TDL(Tunable Diode Laser) can relative easily select the absorption line of the detecting gas without the interference from other gas thus make the rapid and accurate hydrogen sulfide measurement a possible. In this paper, a hydrogen sulfide measurement system is designed and then be carried out in Bonan gas gathering station of (SOF) .The implemented experiments showed the system effectively solved some problems such as overfall, temperature and pressure. After comparing the hydrogen sulfide online detection sensor of the TDLAS industry with the long hydrogen sulfide detection tube, the linear fitted relationship with the correlation coefficient of 99.96% between them was attained. In order to meet the requests of industrial field anti-explosion, the open-path optical coupling technology was performed in china for the first time. All the results demonstrate that the system will be put into use and enjoy a high application in the near future.
