PRISM® VSA - On-Site Gas Generation | Air Products

From glass, frit, metal, cement, water treatment, to pulp and paper, oxygen is a key element in improving process efficiency, quality, and sustainability. PRISM VSA delivers quality oxygen exactly where your industry needs it most. Why generate oxygen on site? Relying on delivered liquid oxygen means dealing with complex logistics, rigid supply schedules. With PRISM VSA technology, you produce your own oxygen directly on site, giving you control over supply, eliminating delivery constraints, and ensuring that we are best prepared to supply your process with what you need, when you need it. How does it work? The process begins as ambient air is drawn into the system by a blower. This air passes through a filtration unit, which removes particulates to ensure only clean air enters the next stage. The filtered air enters two vertical vessels filled with molecular sieves. These sieves selectively absorb nitrogen molecules, allowing oxygen to pass through. The vessels operate in cycles. While one is absorbing, the other is regenerating. The oxygen produced is collected in a buffer tank. This tank maintains a steady and uninterrupted supply of oxygen to your process, even during the cycles of the absorber vessels. Waste gases and water vapor are removed by a vacuum blower. The entire system is fully automated and monitored 24/7. A digital dashboard tracks oxygen purity, system status, and performance, ensuring optimal operation tailored to your specific needs. With Air Products PRISM VSA technology, you get immediate savings on operating costs thanks to optimized energy use and no need for utility water. PRISM VSA adapts to your process with flexible performance and customizable options. And by generating oxygen on site, you reduce your carbon footprint and support a more sustainable industry. With Air Products PRISM VSA technology, on-site oxygen generation becomes simple, reliable, and sustainable. Ready to transform your process?
