Oxygen measurements in natural gas: new application note

A new application note is available to download from Michell Instruments':
Oxygen Measurement in Natural Gas

There are many reasons why oxygen is undesirable in natural gas, on top of meeting the regulatory requirements for purity:

  • Oxygen combines with other chemical gases, especially H2S, to form acids.
  • Oxygen does not add to the heating value of the gas and is not of benefit.
  • Oxygen degrades amine, which inhibits the process of removing carbon dioxide and H2S from the gas chemically.
  • Oxygen can degrade some mercaptans reducing the effectiveness of these odorants in the gas.
  • Oxygen accelerates corrosion in the mechanical components that come in contact with the gas.
  • Oxygen in sufficient quantities and with a heat source can cause explosions.

The application note discusses the various oxygen measurement methods available, along with their benefits and disadvantages.
