Membrane nitrogen generators working principle

Membrane nitrogen generators working principle
First, every nitrogen generator requires a compressor to supply the air from which the N₂ will be separated. A membrane nitrogen generator makes this separation happen with a membrane that consists of thousands of hollow polymer fibers. These fibers have a unique structure that allows only the oxygen and any remaining water vapors in the air to escape through its walls. This process is called permeation.
Water vapors will permeate very quickly; oxygen takes a little longer. Argon and nitrogen permeate rather slowly, meaning that they will remain in the fibers long after the water vapor and oxygen are gone.
Once outside the fibers, the O₂ and water vapor is vented out of the membrane housing and disposed of outside or in a safe area. This leaves the N₂ inside the hollow fibers, ready to be collected at the outlet. With the water vapors removed, the produced nitrogen is very dry, which is an additional benefit for many applications.

Key applications for nitrogen generators: oil & gas, mining, shipyard

The main applications for nitrogen generators are in the oil and gas industry, mining and shipyards
Our nitrogen membrane generators are suitable for every possible application where nitrogen is required. The more nitrogen is required for your specific application, the bigger unit you go for.
The nitrogen generators can cover multiple applications, including under-balanced drilling, pipeline purging and pigging, coiled tubing operations, reservoir pressure maintenance, and fracturing, amongst others.
It’s versatility also extends to mining applications – think extinguishing coal mine fires and inerting abandoned areas, and shipboard applications where the unit’s help to create inert atmospheres in vessels carrying crude oil, chemicals, LNG gas, and LPG gas. This wide range of applications highlights the generators’ adaptability across various industries.
