Air Separation
Adsorbents are used in a range of air separation, purification, and compression applications. Air must go through separation processes to obtain valuable gases at a purity level that must be met whether its oxygen or nitrogen. Argon and other gases in air must be treated to achieve requirement of impurity levels.

Applications
Cryogenic Air Pre-purification
In the United States, material can be disposed of in a licensed landfill. The material is normally analyzed to meet the regulations for proper chemical waste management.
Nitrogen Production
Nitrogen is a valuable gas that is used in many applications from filling rubber tires to powering lasers. Nitrogen can be produced using atmospheric air and can be either adsorbed or rejected during Pressure Swing Adsorption (PSA) processes to create a high purity stream.
Oxygen Generation
Oxygen is generated via a pressure swing adsorption process that results in high purity industrial and medical oxygen gas. Oxygen generation involves a special procedure and adsorbents must meet high quality standards to achieve very low levels of nitrogen.
