Pressure swing adsorption provides the separation of oxygen or nitrogen from the air without liquefaction. The process operates around ambient temperature; a zeolite (molecular sponge) is exposed to high-pressure air, then the air is released and an adsorbed film of the desired gas is released. The size of the compressor is much reduced over a liquefaction plant, and portable oxygen concentrators are made in this manner to provide oxygen-enriched air for medical purposes. Vacuum swing adsorption is a similar process; the product gas is evolved from the zeolite at sub-atmospheric pressure.
Nitrogen Generator (PSA & Membrane Type)
If you are looking for a large capacity nitrogen generation package, and footprint is critical, our frame-mounted N2 generators are quite simply best value for money. The system is plug-and-play and the design is well-proven with well over one hundred installations around the globe.
- Higher quality materials
- Lower energy consumption
- Shorter lead time
- Longer N2 generator lifetime
High capacity nitrogen membrane-type meets the needs of large-volume users. Including manufacturers of steel, food, wastewater treatments, glass, textiles, and pharmaceuticals, as well as oil and gas production.
Engineered for fast installation, high-flow nitrogen equipment is designed by UNISSI to minimize your electrical power consumption. Low maintenance and easy to operate, these nitrogen systems from UNISSI are ideal for a wide range of applications, with significant operational savings.
Weather-proofed self-contained membrane systems are a way of producing a ready-made solution to hold the nitrogen at a lower cost than engineering, designing, and building a structure to hold the PSA and compressor skid.
Operating pressures up to 7 bar (100 PSIG) are normal, to achieve higher pressure up to 24 Bar (350 PSIG), features of the skid-mounted system, is easily transported and provides convenient access for maintenance. Models are available to supply high-volume requirements of up to 5,000 M³/hr (170,000 SCFH with a range of purities of up to 99.9%).
UNISSI supplies a wide range of desiccant air dryers, ideal for pipeline maintenance and other offshore industries.
