How to Remove Oxygen from Natural Gas

Oxygen is present in natural gas as well as in the environment. Liquid petroleum, natural gas, liquid form of the same contains a part of oxygen naturally. Oxygen is contained in a vacuum system, coal mines, and oil recovery systems. Several pipeline techniques require natural gas and they must have a specific amount of oxygen. This may be required in the gas dryers. LPG uses the processing of air to reduce the calorific value and get air balancing. Here, let’s explore the process of removing oxygen from natural gas.


Things to remember before the oxygen removal process


If oxygen is present in natural gas, it can create a hazardous situation. This can create corrosion on the machines, and it will increase the maintenance and replacement costs. Moreover, oxygen reacts with hydrogen sulfide to produce sulfur. Oxygen also forms oxidation of glycol solvents which are used in acid gas removal and drying plants.


  • Types of the oxygen-filled natural gas system: Oxygen can be found in several natural gas sources. These streams include vacuum, traditional pipeline, and so on. Vacuum systems include coal mines, oil recovery systems, and landfills. Traditional pipelines contain 100 ppm oxygen.


  • Purpose of removing oxygen from gas: Oxygen is already present in the natural gas sources and this can create various issues in the machine processes. When you opt for oxygen removal from natural gas, it removes the threat of corrosion on the pipelines and in the machines. If oxygen is not removed it can create damage on the pipelines rendering them useless for future use.


  • Expert’s opinion: Oxygen is difficult to extract from natural gas. It requires high-end technologies that are either not available or not yet discovered. On the other hand, the market opportunities are limited as well. It can cost a few thousand bucks for the removal project, and there are insufficient methods.


Oxygen removal processes from natural gas: 


Few processes can be followed to separate oxygen from natural gas. Although they are costly, it’s not impossible.


  • Natural Gas BTU Rating of natural gas: To extract oxygen from natural gas, it’s important to check the British thermal unit of the gas. With this system, oxygen can be removed without spending much after the project. Companies are opting for this option to get tax breaks and subsidies. However, there is no single procedure that has achieved the full-proof result.


  • Landfill Gas recovery: This is a very costly and risky recovery technique and requires modern equipment. However, you can earn great revenue from the recovery process. In recent days, some companies are offering catalyst-based procedures for the removal of oxygen from natural gas.


  • Sieve or molecular gate process: This process includes pores of similar sizes to the gas. This helps to separate the gases. This is a new technology, and it requires further development. Also, the price is quite high.


Metal treatment is another process of oxygen removal from natural gas. In this procedure, a stream of hydrocarbon gas is channeled over the metal, this allows the oxygen in the gas to react with the metals and separate. Different types of metals can be used such as silver, nickel, iron, copper, and cobalt.

How To Remove Hydrogen Sulfide

Hydrogen sulfide is a byproduct and a pollutant gas. It is produced by various industrial processes. These include oil drilling and various other such processes. This is a health hazard and inhaling large quantities of this gas could lead to unconsciousness and even death in a few cases. There are instances where even inhaling of small quantities could lead to health challenges and many physically weak persons could also face the danger of death or permanent disability. Hydrogen sulfide gives out a foul odor that resembles a rotten-egg. It is very powerful and can be noticed even in small quantities of 2 parts per billion. This is perhaps equal to around 1 milliliter of gas in a lecture hall that can seat 100 people. Hence, it is quite important to find out ways to neutralize this gas during and after the completion of the manufacturing and other processes.

 How Is Neutralization Done?

 Sodium bicarbonate solution is considered one of the best options for neutralizing Hydrogen sulfate. Sodium bicarbonate in the recommended quantities has to be dissolved in water. There are a few other salts such as potassium bicarbonate and sodium bicarbonate which also could work. Sodium bicarbonate is the best option because it is very stable and highly soluble in water. It works well in small quantities. A solution of sodium bicarbonate of 0.01 grams to 0.25 grams per mole of water is good enough to neutralize hydrogen sulfide.

 The Right Process Has To Be Followed

 There are some laid down protocols, methods, and processes when it comes to removing hydrogen sulfide from different sources. The same must be followed strictly. It would always be advisable to have this process done by professionals rather than trying it yourself. A gas containing carbon dioxide and hydrogen sulfide should be brought in contact with water that is laden with baking soda or calcium bicarbonate. This can be done in many ways including spraying of the water solution over the container that contains hydrogen sulfide amongst other gaseous substances. You could also send the gas bubbling through a vessel holding the water that has the right mixture of sodium bicarbonate.

 It Is Complex And Difficult

 However, we need to bear in mind that it is a highly complex and difficult job and doing it without the right protection and expertise would not be the best way forward. Many professionals could help in finding out the right solution and approach that could help in removing hydrogen sulfide from biogas, water, oil and other sources. There are also other absorbents in the form of powder and liquids that could also be tried out. But at the end of the day, there is no denying the fact that it is essential and vital to ensure that the main product is made free during and after the manufacturing and conversion process. The harmful side effects are quite dangerous and they have been mentioned earlier in the article. Hence, there cannot be any compromise on this under any circumstances. Professional approach with the right tools and methods is the best way forward
