Gas fields infected with oxygen can be found all over the world, with landfill gas being the most frequent. It is necessary to remove oxygen from natural gas. This patent-pending technique can treat gas at any amount or O2 content while being simple to operate and low in cost.

Oxygen-contaminated gas streams come in a variety of shapes and sizes. Oxygen is present in a variety of natural gas streams. Vacuum devices and typical pipeline systems are examples of contaminated streams. Dumpsites and coal mine methane are examples of vacuum systems that can carry several percent oxygens, whereas standard pipelines may only have 100 ppm of o2.

Why is it necessary to eliminate oxygen from natural gas?

When oxygen removal from removal gas is detected in a gas, it can create a variety of issues, including the breakdown of process chemicals (e.g. amine), increased pipeline corrosion, and exceeding pipeline standards of 10 ppm. These gas streams are typically abandoned, but the X-O2 technology can treat them to make them useful and profitable again nonionic surfactants.

Systems for Removing Oxygen 

Oxygen removal devices are rarely used, and these gas streams are often discarded or mixed to meet pipeline requirements. The scarcity of oxygen removal systems in the natural gas sector is due to several factors, like high capital costs, an absence of industrial competence, and a low oxygen extraction range.

Oxygen Removal Technologies

A stand-alone system removes oxygen from natural gas using a catalytic reactor and is typically used as the final stage in the waste gas filtration process. Because biogas has a high water content as it departs the reactor, it must be dehydrated, which is commonly accomplished using a TSA method or a desiccant dryer.

Oxygen Removal Requirements

The hydrogen sulfide removal from biogas natural gas is dangerous because it can enable processing machinery to corrode, raising upkeep and replacement costs. Furthermore, oxygen becomes sulfur when it combines with hydrogen sulfide. Oxygen affects purge streams by oxidizing glycol liquids used in drying facilities or creating salt in acid gas removal devices.

Expert Insight

Natural gas is hard to differentiate from oxygen. Not only is the science lacking in terms of development and availability, but the market potential is deemed to be restricted. The sector has yet to establish experience and competence due to the high expense of such a removal operation and a lack of adequate channels.

Natural Gas BTUs

The industry is currently pursuing landfill gas recovery facilities to create BTU gas to be delivered through the pipeline because of rapidly rising energy costs. Even without the subsidies and tax incentives, this is becoming an appealing option.

The bigger hydrocarbons are preferred since they require lesser temperatures for the reaction to take place. This enables larger oxygen levels to be treated in streams containing heavier hydrocarbons than in channels containing simply methane as the source of energy. Hydrogen sulfide removal is used as a source of fuel in some cases. Supplemental hydrogen can be injected into the gas stream to assist the oxygen removal from natural gas if it is not already present in adequate volumes.
