Prism Membrane System Standard Layout

The air that we breathe contains 78% nitrogen, 21% oxygen and 1% other gases. The PRISM Membrane System uses this unlimited supply of raw material to produce specific purities of nitrogen

The air that we breathe contains 78% nitrogen, 21% oxygen and 1% other gases. The PRISM Membrane System uses this unlimited supply of raw material to produce specific purities of nitrogen.

Selective permeation is the general principle behind the membrane system. Each gas has a characteristic permeation rate that is a function of its ability to dissolve and diffuse through a membrane. This characteristic allows "fast gases" such as oxygen to be separated from "slow gases" such as nitrogen.

The key component of the system is the PRISM Alpha Membrane Module. Each module contains thousands of hollow fibre membranes, which allow the oxygen, water vapour, and carbon dioxide in compressed air to be selectively removed resulting in a nitrogen-rich product stream. By adjusting the airflow rate through the membrane module, different nitrogen purities and flow rates can be produced.

Flexibility in your nitrogen supply

• Controlling the air-flow through the system will allow you to achieve various flow and purity levels.
  
• Future increases in nitrogen demand can be accommodated by adjusting the controls or by simply adding modules.
  
• Our systems are so versatile and flexible that they can be made to operate in extreme conditions of temperature and pressure.
  
• The PRISM Alpha Separator’s membrane fibres and shell are designed for the most demanding applications.
  
• The light weight compact design makes a PRISM system ideal for space and weight sensitive applications such as in offshore, shipboard and other mobile or remote locations.
