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.
