PRISM Nitrogen Membrane
PRISM® PA Membrane Separators
Description
PRISM® PA nitrogen 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 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.
Structure
A typical membrane separator contains thousands of fibers that are bundled and encased at both ends in epoxy resin. The ends of the bundle are cut, which leaves the fiber bores open on both ends, allowing the gas to travel from one end to the other. The fiber bundle is enclosed in a suitable casing. The casing protects the fibers and routes the gas properly.
Air Products' PRISM® membranes: experience, performance, and value.
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.

PRISM® PA Membrane Advantages
A PRISM® PA membrane separator's primary role is to separate compressed air into nitrogen. The majority of applications are to generate nitrogen for use as an inerting gas to eliminate flammable atmospheres or to preserve items that oxidize in air. PRISM® PA membrane separartors are assembled with N1, N2, or P3 membrane fibers. The PA membrane separators will generate nitrogen purity up to 99.9%.
N1 fiber is used in applications where high volumes of nitrogen are required from the system. Application examples include inerting produce warehouses and cargo holds of ships, inerting oil and gas transport ships, hypoxic air, fire prevention and dozens of other applications where nitrogen is used.
N2 fiber is similar to N1 but is used where there is extreme cycling of the membranes. Applications for N2 fiber include beverage dispensing and tire filling applications.
P3 fiber is a highly selective membrane. This membrane has a lower volume throughput when compared to the N1 fiber, but it produces more nitrogen per volume of compressed feed air. The P3 fiber has the highest selectivity that is commercially available. This is used where compressed air is limited or power resources for generating input air need to be conserved. Application examples include off-shore oil platforms and marine use.
Benefits
• Quality assured - Every membrane separator has to pass our rigorous testing requirements before it will be released into service. You can be confident that every separator will perform as advertised. AS9100 certification meets the exacting requirements of the global aerospace industry for quality management systems.
• Industrial grade - PRISM membrane separators are designed to handle industrial production loads. Pressures up to 24 barg ensure that your nitrogen production requirements will be met. The solid construction is a perfect match for remote and severe duty installations like oil platforms and mining operations.
• Passive technology - The selective permeation technology uses a passive system with no moving parts. This simple system allows you to engineer more reliable products that can be deployed in a wide range of environments, including mobile systems.
• Simple start-up - PRISM membrane separators are easily commissioned. Simply apply clean compressed air, and production begins. No break-in period, expensive media, or complex equipment to manage and maintain.
• Lightweight - PRISM PA membrane separators are constructed from high-performance ABS or 6061/6063 aluminum, which makes them very lightweight. Separators are easily handled by one person, making installation and field service simple.
