Membrane Solutions for Marine Nitrogen Generation

Our Differentiator
Our shipboard nitrogen membrane systems utilize thousands of hollow polymer fibers that are bundled together to form a membrane separator. Compressed air is then fed to the bore side of the separator. As the air flows inside the fibers, oxygen, carbon dioxide, and water vapor molecules permeate faster than nitrogen molecules through the membrane walls to the low-pressure side of the fibers. The bore-side air is gradually depleted of the fast gases, consequently increasing the nitrogen percentage. The final product can be used directly or stored for later usage.
Our Solutions

Our shipboard systems are fully turnkey. Air Products Membrane Solutions takes full responsibility for the entire system, from nitrogen generators, feed air compressors, and boosters to panels, DBB, bottles, buffer vessels, and more. Our solutions for marine nitrogen generation include:
