Standard methods and related techniques for on-line detection of the total sulfur content in natural gas

At present, many domestic total sulfur detection methods are accurate and reliable, but they are disadvantageous with a low detection frequency, a long detection period and delayed work. In this paper, the standards of the total sulfur content detection of natural gas were reviewed. Then, the standard methods and related techniques for on-line detection of the total sulfur contents in natural gas were discussed, and their principles were figured out. And finally, it was recommended to develop a domestic on-line detection standard method for sulfur compounds and the total sulfur contents in natural gas. It is concluded that on-line total sulfur content detection is the inevitable development trend in the future; and that there is neither methods nor standards at home available for on-line detection of the total sulfur contents in natural gas, so it is recommended to timely formulate a national standard correspondingly by referring to foreign standards, e.g. ASTM D7165-10(2015), ASTM D7166-10(2015) and ASTM D7493-2014.
