Removing the Oxygen Out of Natural Gas

Do you wish to learn more about the deoxygenation of natural gas? Then you are in the appropriate location. You will find numerous advantages and all the information you require regarding oxygen removal from natural gas in this post. Both the environment and natural gas streams contain oxygen. All three types of gas—natural, liquefied petroleum, and liquefied natural—have some oxygen in their free natural form. The vacuum system comprises coal mines, oil recovery systems, and landfills, including oxygen. According to numerous pipeline requirements, natural gas must have less than fewer parts per million of oxygen. Different natural gas surges, sometimes known as polluted gas streams, include oxygen. However, traditional channels could only contain 100 ppm of oxygen. cleaner formulation It is possible to add or provide oxygen when utilizing gas dryers. It must be treated with air to reduce the calorific value of LPG and create air balance. As landfill gas is extracted, oxygen that is present in it is drawn into the dump.

Why Does Natural Gas Need to Have the Oxygen Removed?

Natural gas with oxygen should be avoided since it might corrode processing equipment, increasing maintenance and replacement expenses. Additionally, when oxygen and hydrogen sulfide combines, oxygen turns into sulfur. By oxidizing the glycol solvent used in drying plants or producing salt in acid gas removal systems, oxygen also has an impact on purge streams. Oxygen, a natural gas stream, can lead to several problems, such as the breakdown of process chemicals (such as amine), increased pipeline erosion, and exceeding the ten ppm limit for pipelines. It is challenging to isolate oxygen from natural gas. In addition to the technology’s lack of advancement and accessibility, the market’s potential is also thought to be constrained. Due to the high cost of such a removal project and the absence of suitable channels, the sector has yet to acquire expertise and competence.

Oxidation Catalytic

Directing a natural gas stream over a catalyst bed at a higher temperature can remove oxygen from the gas. Natural gas and oxygen combine to produce CO2 and water. Natural gas is used as the fuel in the catalytic “burn” of oxygen to produce CO2 and water. Since the reaction can occur at lower temperatures, heavier hydrocarbons (propane+) are favored. This makes it possible to process heavier hydrocarbon streams with more substantial oxygen concentrations than streams with just methane as the fuel source. In some circumstances, hydrogen non ionic surfactant can serve as a fuel source. If sufficient amounts of hydrogen are not already present, additional hydrogen can be added and injected into the gas stream to promote the reaction. Two of hydrogen’s main benefits are lower reaction temperature and less potential for secondary reactions.

Advantages of Taking The Oxygen Out of Natural Gas

  • Handles gases of any volume or oxygen content.
  • Operational simplicity
  • Economical
  • Exceptionally trustworthy
  • The oxygen content falls below detectable levels.
