Membrane technology is recognized as a burgeoning gas separation method within the industry, offering lower initial capital and energy consumption costs when compared to cryogenic distillation and pressure swing adsorption. In the typical design of membrane gas separation, ambient air is drawn into the membrane module, and the targeted gases are separated based on differences in diffusivity and solubility.
Within the membrane module, oxygen is effectively separated from ambient air and gathered at the upstream due to its high diffusivity. Conversely, nitrogen is collected at the downstream of the module. This process allows for an efficient and cost-effective means of gas separation in various industrial applications.
A nitrogen generator employing membrane technology possesses the following features:
1. Cost-effective method for nitrogen production.
2. Capable of producing nitrogen with high purities or generating higher volumes of nitrogen at lower purity levels.
3. Enhanced reliability attributed to a straightforward airflow design.
4. Operates at lower operating and delivery pressures, contributing to efficiency and ease of use.

Our PSA Nitrogen Gas Generators Are Widely Used Across Many Industries Including:
Inflating rubber tires with nitrogen significantly extends tire lifespan by reducing oxidation and minimizing leakage, resulting in more stable pressure maintenance.
The presence of air in fuel tank headspace can lead to the formation of a flammable mixture, and the flammability risk can be mitigated by purging and filling fuel tanks with nitrogen.
Utilizing nitrogen in autoclaves and furnaces can lower the risk of flammability and combustion.
Nitrogen gas is ideal for applications demanding minimal oxygen presence or an inert atmosphere.
The presence of air in fuel tank headspace can lead to the formation of a flammable mixture, and the flammability risk can be mitigated by purging and filling fuel tanks with nitrogen.
The safe handling of volatile chemicals and petrochemicals necessitates the presence of nitrogen to ensure the secure management of process gases or liquids throughout different stages of handling.
Large laboratories with a centralized gas supply system experience continuous gas availability through the use of on-site generators for nitrogen and hydrogen.
Nitrogen is indispensable for fire prevention when dealing with highly flammable crudes and volatile gases due to their handling requirements.
The storage and transportation of oil and crude substances entail risks, necessitating the use of nitrogen to establish a fire-safe environment.
