Membrane nitrogen generators operate on the principle of selective permeation. Different gas components in air exhibit distinct solubility and diffusion rates when passing through polymer membranes. Fast-permeating gases are separated from slower-permeating components, such as nitrogen, by exploiting this property.
1. Offshore oil platforms：
Produces inert nitrogen for explosion prevention and oxidation control, ensuring operational safety.
2. Oil tankers (oil–gas displacement)：
Displaces flammable gases in cargo tanks to eliminate explosion risks during transportation.
3. Vehicle-mounted mobile nitrogen generator：
Compact and flexible, enabling on-site nitrogen supply for temporary work sites.
4. Field military applications：
Rapidly generates nitrogen for field operations, equipment protection, and explosion prevention.
