Experience and technology are just two of the things you can count on with on-site gas supply from Air Products. PRISM® PSA systems also deliver fast and easy installation and integration to your operations as well as reliable and dependable nitrogen supply from an integrated system of gas generation and liquid backup for peak shaving.
Let us design the optimal, made-to-measure nitrogen on-site gas generation system and work with you for the lifetime of your nitrogen gas needs whether under a long term gas supply contract or with plant services and technical support under an equipment sale agreement.
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
- 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.
