Monitoring Hydrogen Sulphide (H2S) Corrosion in Oil & Gas Upstream Industry

Overview The dangers of Hydrogen Sulphide (H 2 S) aka Sour Gas in oil and gas production are well known. A highly toxic, corrosive, flammable and explosive gas. H2S is colourless and although characterised by it “rotten egg” smell, at high concentrations can also be odourless. H 2 S poses an extreme risk to health and safety of personnel. Exposure can result in serious short term and long terms effects, including...

Choosing the Right Gas Analyzer for Nitrogen Oxide (NOx) Emissions Monitoring

NO x is probably the most ubiquitous combustion-created air pollutant since it can be generated by any process burning any fossil fuel, and it is tightly regulated by the U.S. EPA and other regulatory bodies around the world. Plants with relevant combustion processes, including most refineries and chemical processing plants, must monitor NO x output continuously any time fuel is burning. How plants choose to do this...
