Mining of coal, oil and natural gas

Huilin on-site PSA (pressure swing adsorption) nitrogen generator can be widely used in coal, oil and natural gas applications, including fire prevention, fire fighting, pipeline cleaning, purging, covering, combustible gas protection, transportation, drilling operations and improving oil recovery.

The essence of nitrogen injection fire prevention is to inject a certain flow of nitrogen into the oxidation area or fire hazard area of the goaf to reduce the oxygen content to 10% or less than 3%, so as to achieve the purpose of fire prevention and extinguish gas explosion.

In coal mines, when a fire occurs in the oxidation area of the goaf, the biggest disaster is the explosion of the internal mixed gas. It can be seen from the explosion triangle of the mixed gas that if the oxygen content in the mixed gas is less than 12%, the explosion can be reduced, so Huilin is injected ® Nitrogen will inhibit the explosion. At the same time, the oxygen content can be reduced below the critical value of coal spontaneous combustion, so as to prevent coal spontaneous combustion.

Nitrogen is a standard gas used to re-pressurize oil and gas from Dajing/natural gas reservoir. Using the characteristics of nitrogen to maintain reservoir pressure, mixed phase and immiscible oil displacement and gravity drainage technology can greatly improve oil recovery, which is also of great significance to stabilize oil production and increase oil production.

Before maintaining or loading the oil and gas pipeline, there are still some flammable and explosive gases inside, so you must use HUILIN ® The on-site PSA nitrogen generator produces qualified nitrogen to clean and purify the pipeline to ensure the safety of all processes.

The residual air on the top of the fuel tank is the main cause of fire and explosion of the fuel tank. The basic method to solve this problem is to fill the top of the fuel storage device with nitrogen to replace the internal air, so that the oxygen content is lower than the safe level.

The on-site PSA nitrogen generator provided by HUILIN has nitrogen purity ranging from 95% to 99.9995%. Please contact us for more information.
