Removal Of Oxygen from Natural Gas – Facts You Need to Know

Oxygen is found in many different types of natural gas streams. These streams are called contaminated streams. Streams are found in two classes: vacuum systems and traditional pipeline Systems. The vacuum system includes land fails, coal mines, and vacuum oil recovery systems. They contain several points of oxygen, and conventional pipelines may have only 100 PPM of oxygen. When oxygen is recognized in a natural gas stream, it causes several problems, including increased corrosion in pipelines, degradation of process chemicals, and exceeding specifications usually set at 10 PPM.

Oxygen Contamination Factors

Traditional natural gas and gas produced in oil fields do not contain oxygen. Typically, air infiltration during the gathering or processing causes it to become engaged. Several potential pathways by which oxygen enters the body from air intrusion include:

  • Vapor recovery units with tanks that are improperly regulated.
  • An inadequate or non-existent tank blanketing structure.
  • Low-pressure air is drawn into the compressors through their internal workings.
  • Seeping well casings, fitting, and pipe leaks in the vacuum collection system.

 

Due to the rising global need for energy, some non-conventional natural gas deposits are in higher demand. One such conventional foundation is coal mine methane, or CMM, produced by the geologic process of coalification, in which coal and methane are combined.

The Need for Oxygen Removal

Natural gas with oxygen in it has several drawbacks. It can worsen pipeline corrosion and degrade process chemicals like amine and many other things. It is dangerous and can also damage the entire piece of machinery, raising the cost of repair and new equipment. Additionally, it creates sulfur when it interacts with hydrogen sulfide. Additionally, it oxidized the glycol solvents used in drying plants and eliminated acid gas. The presence of oxygen hurts the unit’s handling of amine, glycol, and sieve molecule dehydration during gas processing. Glycol breakdown processes involving dehydration are catalyzed by oxygen, and the resulting products may include polymers, acids that promote corrosion, and aldehydes. In systems that treat amine, oxygen combines with alkanolamines to generate heat and temperature stable salts. Their presence reduces the amount of amine available to remove acid gas, further speeding up corrosion rates. When spent amine is dumped, it could endanger the environment since the replacement cost of chemicals used to treat amine rises when oxygen is present. To prevent this, it is crucial to remove oxygen from natural gas. And sulfur removal from natural gas.

Conclusion

Oxygen removal from natural gas is not an easy task. It takes a lot of effort to remove oxygen from natural gas. Oxygen removal project is costly and lacks avenues. The oxygen removal industry has to develop itself with more friends and expertise so that it doesn’t seem like a headache in the future. We can take this seriously because it offers physical and environmental concerns not only because of the lack of development and availability of Technology but also because of the Limited perceived market opportunities. It is essential to remove oxygen in natural gas for a healthy environment. It is highly reliable and reduces oxygen concentration to a nondetectable level. hydrogen sulfide removal from natural gas
