Best Offer Prism PA Nitrogen Membrane Separators

Prism PA nitrogen membrane separators

Prism membrane separators are used to generate high-purity nitrogen from compressed air. These robust and durable separators use hollow fiber membrane technology to molecularly separate nitrogen from other components in compressed air. The resulting stream of nitrogen is pure,dry, and ready to use in most industrial applications.

Every Prism membrane separator is hand assembled and tested in our AS9100 certified facility. You can be confident that each separator will perform as promised.

How membranes work

The PRISM PA nitrogen membrane separator uses asymmetric hollow fiber membrane technology to separate and recover nitrogen from compressed air. Atmospheric air contains 78% nitrogen, 21% oxygen, and 1% other gases.

The PRISM PA membrane uses the principle of selective permeation to produce high-purity nitrogen. Each gas has a characteristic permeation rate, which is a function of its ability

to dissolve and diffuse through a membrane. Oxygen is a “fast” gas and is selectively diffused through the membrane wall, while nitrogen is allowed to travel along the inside of the fiber, thus creating a nitrogen-rich product stream. The oxygen-enriched gas, or permeate, is vented from the membrane separator at atmospheric pressure. The driving force for the separation is the difference between the partial pressure of the gas on the inside of the hollow fiber and that on the outside.In the PRISM PA membrane separator, compressed air flows down the inside of hollow fibers. Fast gases—oxygen, carbon dioxide, and water vapor— and a small amount of slow gases, pass through the membrane wall to the outside of the fibers. They are collected at atmospheric pressure as the permeate. Most of the slow gases and a very small amount of the fast gases continue to travel through the fiber until they reach the end of the membrane separator, where the product nitrogen gas is piped to the application.
