PSA nitrogen generators are an economical and fast way to obtain high-purity nitrogen. They are widely used in the oil industry. Whether it is the efficiency and safety of oil and gas production or the safe maintenance of oil and gas pipelines, nitrogen can be seen in almost every link.

Perhaps many people think that the use of nitrogen is nothing more than to help maintain oil layer pressure and store gas during oil and gas production; but in fact, the uses of nitrogen are not limited to these. It is also widely used in secondary and tertiary oil production, purging of oil and gas pipelines and equipment, and as a protective gas for the transportation of flammable and explosive items.

1. Increase the production of oil and gas layers

Taking advantage of the low density of nitrogen, injecting it into the top of the structure or allowing it to migrate to the top of the structure can enhance the downward displacement of oil layer fluids or gravity, stabilize the mixed phase plug, and increase the production of oil and gas layer fluids.

2. Maintain pressure

Nitrogen is a standard gas used to re-pressurize oil and gas from large wells/natural gas reservoirs. It can use its own characteristics to maintain oil layer pressure.

3. Storage gas

According to the characteristics of inert gas, nitrogen is used to establish an inert atmosphere for the processing, storage and transfer of flammable materials.

4. Purging of pipelines and equipment

Nitrogen can be used to perform air pressure leak detection and purge the oil and gas pipelines. If the oil and gas transmission pipeline needs to be repaired, it is necessary to purge the pipeline with nitrogen at a certain pressure and flow rate according to the actual situation of the pipeline. There may be some flammable and explosive gases to ensure safety.

5. Fire and explosion prevention

For the fire hazard area in oil and gas production, a certain flow of nitrogen can be injected into the area to quickly reduce the oxygen content in the area to below 5%, so as to achieve the purpose of fire prevention and explosion prevention. In addition, the residual air on the top of the oil and gas storage tank is one of the main causes of oil tank fire and explosion. Filling the oil tank with nitrogen can solve this safety hazard, and this method is also used for other liquid storage tanks.

In fact, no matter what kind of production, including oil and gas operations, the most important thing is to ensure the safety of production; and the use of nitrogen in oil and gas production can not only increase efficiency, but also improve the safety factors of various productions. It can be seen that the use of PSA nitrogen generators in oil and gas production is not only extensive but also important.
