Abstract

Abstract: Aiming at the problem for the ultraviolet absorption method in the determination of hydrogen sulfide content in natural gas, is still lack of national standards, a series of comparative tests of the instruments are carried out in different institutions, and data are processed according to Petroleum products–Determination of precision data in relation to methods of test(GB/T 6683-1997), requirements of the repeatability and reproducibility of UV absorption method for determination of hydrogen sulfide content are obtained, and the determination of the test results is made clear, which plays an important role in the preparation of the national standard of this method. At the same time, the comparative experiment with iodometric method is also used in the study. The results show that, compared with the artificial chemical titration method, the ultraviolet absorption method can control more influencing factors at a lower random level through the instrument, so it appears more stable and controllable. In addition, the continuous stability test data of 7 months show that stability of the test this method is excellent, and it has the long-term stability and accuracy requirements for online monitoring of hydrogen sulfide content in pipeline gas.

Key words: natural gas, ultraviolet absorption, hydrogen sulfide, reproducibility, repeatability, on-line monitoring
