Pressure Swing Adsorpt1ion (PSA) Oxygen

4.

A ir contains 21'% oxygen, 78% nitrogen, .9% argon, and .1% other gases. AirSep Oxygen Systems separate

this small percentage of oxygen from compressed air through a unique Pressure Swing Adsorption (PSA) process. The PSA process uses molecular sieve (a synthetic zeolite), which attracts (adsorbs) nitrogen from air at high pressure and releases (desorbs) it at low pressure.

AirSep Oxygen Generators and Oxygen Plants use two vessels filled with molecular sieve as adsorbers. As compress­ed air passes through one of the adsorbers, the molecular sieve adsorbs the nitrogen. This allows the remaining oxygen to pass through and exit the adsorber as a product gas. Before the adsorber becomes saturated with nitrogen, the inlet air flow is switched to the second adsorber. The first adsorber is now regenerated by desorbing the nitrogen through depressurjza­tion and purging it with a small amount of oxygen. The com­plete cycle is then repeated. Under normal operating condi­tions, the molecular sieve is completely regenerative and will last indefinitely.

From 4-60,000 SCF/hr (.11-1,577.4 Nm3/hr), AirSep offers a wide variety of PSA oxygen systems to supply virtually any oxygen application.

Tonnage Plants

Standard or Custom Design

Standard oxygen plants are available in either low pressure power-optimized or high pressure cost-optimized designs. Low pressure plants generate 90% pure oxygen at up to 15 psig (105 kPa) and consume approximately 400 kWh ' per ton of oxygen. High pressure plants generate 90% pure oxygen at up to 45 psig (310 kPa) without the use of an oxygen compressor. They consume approximately 750 kWh ' per ton of oxygen,

Custom-designed oxygen plants oller oxygen purities from 60-95%. An optional oxygen compressor delivers the oxygen at pressures up to 3,000 psig (20,685 kPa). t. Power consumption based on per ton (2,000 Ib) of total product generated.

Purchase Options

Customers can purchase turnkey oxygen plants or technical recommenda­tions, including detailed drawings. If requested, AirSep will also supply critical components (e.g. , valves, molecular sieve, plant controls, etc.).

The fabrication of adsorbers and piping can be accompl ished locally under AirSep supervision. In addition, customer-supplied feed air equipment and/or oxygen com­pressors that meet AirSep specifications may be used. AirSep engineers direct the (inal testing and start-up of the plant.

Easy Installation

AirSep designs oxygen plants for easy installation. The valves, manifolds, and plant controls are preassembled in our facility and delivered on skids. Adsorbers are shipped separately for final on-site assembly. Plant assembly and start-up are normally com­pleted in less than five days.
