How to analyze H2S, all Mercaptans, THT as well as total sulfur for monitoring natural gas or gaseous fuels in metering station?
Natural gas is colourless and odourless in its most pure form. When extracted, it can contain sulfur compounds such as H2S and Mercaptans that when in the presence of moisture can produce sulfuric acid that can degrade the pipeline. So for reasons of public safety as well as pipeline integrity, there is a need to measure and control precisely the level of odorant species in natural gas :
- adjust the amount of sulfur molecules in the gas
- control of odorant passivation
- aids in detection of leaks
For more than 30 years, Chromatotec® has manufactured the energyMEDOR, based on the gas chromatography principles, to measure H2S, all mercaptans, sulfides, Tetrahydrothiophene (THT) and total sulfur in natural gas. Due to the advantages of the “MEDOR” technology, a new guideline was defined, ASTM D7493-08 (as the Standard Test Method for Online Measurement of Sulfur Compounds in Natural Gas and Gaseous Fuels by Gas Chromatograph and Electrochemical Detection). The energyMEDOR by Chromatotec® is fully compliant with this guideline.
