Specialized Gas Purification

In addition to Xebec’s expertise in designing and building air and gas drying solutions, Xebec accepts commissions to evaluate and create specialized gas treatment solutions to meet a variety of specific needs.

 

Adsorption technology can be applied to many industrial gas treatment processes including biogas separation and purification, hydrogen recovery, air separation, and oxygen enrichment for medical applications, as well as drying applications for air, natural gas, carbon monoxide, carbon dioxide, sulfur dioxide, acetylene, propylene, propane, syngas, and more.

Xebec has developed custom drying or impurity-removal solutions for:

Helium Purification

Helium, a scarce, non-renewable gas, is used in the production of fiber optic equipment and semiconductors. Other industrial uses of helium include optoelectronics, laser welding, cold gas spraying, chemical processing and leak detection. Rising demand and declining reserves of helium have led to dramatic increases in the price of helium, intensifying the market for helium recovery systems. 

The He-3200 combines patented rotary valve pressure swing adsorption (PSA) technology and conventional beaded adsorbents with an optimized PSA cycle to deliver higher helium recovery performance than conventional PSA systems. The Xebec He-3200 requires only one quarter of the space of a conventional PSA and, with only two valves, is simpler to operate. 

The He-3200 provides a compact, cost-efficient solution for the recovery and recycling of helium in leak testing, metals deposition processes and fiber optic and semiconductor manufacturing facilities.

Sulfur Dioxide Drying

Xebec’s HRS-SGX platform is adapted to achieving a -40 °C dew point, which translates into less than 50 mg of water per kg of liquid sulfur dioxide.

Carbon Dioxide Removal from Air

Xebec’s HRS-SGX adsorption purifier is designed to remove carbon dioxide from air. From an air flow of 12,000 scfm, our adsorption purifier reduces CO2 from levels of 400 ppm down to 20 ppm, all on a footprint that is two-thirds smaller than conventional adsorber designs for similar applications.
