Standard methods and related techniques for on-line detection of the total sulfur contents in natural gas
摘要
Abstract
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.Standard Practice for Gas Chromatograph based On-line/At-line Analysis for Sulfur Content of Gaseous Fuels (ASTM D7165-10 (2015),Standard Practice for Total Sulfur Analyzer based On-line/At-line Analysis for Sulfur Content of Gaseous Fuels (ASTM D7166-10 (2015)),and Standard Test Method for Online Measurement of Sulfur Compounds in Natural Gas Gaseous Fuels by Gas Chromatograph and Electrochemical Detection (ASTM D7493-2014).关键词
