Lasergas PSA Technology Overview

Air is 78% nitrogen and 21% oxygen. The Lasergas line of generators employ Pressure Swing Adsorption (PSA) technology to produce oxygen and nitrogen using ambient air and electricity as raw materials. The PSA system is composed of the following components:

• Compressed air system (includes an air compressor, air dryer, air receiver tank and filters)
• Two vessels filled with adsorbents, a Carbon Molecular Sieve (CMS) and Zeolite Molecular Sieve (ZMS) for nitrogen and oxygen, respectively.
• Purification modules
• Product gas receiver tank
• Product gas pressurization equipment and/or bottle filling station
• Control system

In PSA technology a specific gas species is separated from a mixture of gases under high pressure and at ambient temperature by passing the pressurized air through an adsorbent. The separation of gases is based on their different affinity for the adsorbent. At high pressure more gas is adsorbed, and when the pressure is reduced the gas is again released. The adsorbents we use are ZMS and CMS for oxygen and nitrogen, respectively. Under normal operation conditions these molecular sieves are subject to practically no wear, and thus have minimal servicing requirements. The straightforward design and construction of the units guarantee their reliability. Please see more detailed information on nitrogen and oxygen production with PSA technology here.
