PRISM® Pressure Swing Adsorption Process Overview

PRISM PSAs can economically produce nitrogen gas at flowrates from less than 2,000 scfh to greater than 60,000 scfh at purities of 95-99.9995%.

Air Products’ pressure swing adsorption technology consists of four main operations:

  • Air compression
  • Air pretreatment
  • Adsorption/desorption
  • Product delivery

PSA systems compress an air stream, which passes through filters before flowing to adsorption vessels that adsorb the oxygen molecules and allow nitrogen to pass through at the desired purity. Automatic cycling of the two beds enables continuous production of nitrogen.


PRISM® PSA Systems – Optimized Nitrogen Production

Fast and Easy Installation, Integration, and Start-up

Compact footprint, skidded design, and fully automated controls make PSA systems an easy decision for on-site nitrogen generation

High Reliability for Dependable Gas Supply

Fully integrated on-site production and liquid backup systems provide higher on-stream supply reliability, and 24/7 remote monitoring and support brings rapid troubleshooting and enhanced safety to your operations

Low Operating Cost

Proprietary adsorption process and turndown capabilities minimizes power consumption and enable rapid response to changing production needs; all while requiring minimal overall system maintenance cost

Applications Support and Operational Excellence Closer to You

Let our team of industry experts and applications engineers audit your existing supply system to identify gas optimization and cost-saving solutions, improving your operational performance and saving you money long-term
