| Latest Innovations Constant R&D to develop newer and better models high in efficiency, yield and recovery rate has resulted in a model for Oxygen production with Oxygen concentration about ten times larger than those of commercialized PSAs. It was achieved by small-scale equipment using zeolite 5A with a oxygen production capacity of 100 Nm3-product gas/m3-zeolite/hr. A second generation unique Ultra Rapid cycle Psa purification system for Hydrogen gas was developed recently that has rotary adsorbent beds supplanting the rotary valve concept. The rotary adsorbent beds comprises multiple beds within one cylindrical adsorber unit. This latest configuration has resulted in:

As separation technologies of gas mixtures by the process of Pressure Swing Adsorption (PSA) is gaining more and more industrial acceptance as a viable alternative to other methods, the question that is certain to come is What makes PSA or Pressure Swing Adsorption Technology? the automatic choice in gas separation. Following are the key driving forces behind the success, innovation and breakthroughs in adsorption technology.
- A large extent of extra freedom in terms of Thermodynamics in comparison to techniques of absorption and distillation. Because of the adsorbent's presence.
- Optimum results ensured by an unique match between adsorbent and very efficient process designs.
- Numerous classes of porous adsorbents that are available, offers an exhaustive range in kinetic, equilibrium and energetic properties.
- Possibility of different dimensions (i. e, numerous combinations of processes and materials) that can achieve similar separation performance.
- Low energy requirements
- Low capital investment cost
Emerging Technology in PSA Application:
- Fuel cell technology:
As Fuel Cell technology is gaining popularity as commercially viable option, gas purification technology is increasingly applied to several existing and emerging markets. This includes industrial hydrogen production and automotive fuel cells. Pressure swing adsorption technology is steadily gaining acceptance as the numerouno choice in the purification process needed for the emerging Fuel cell market.
Fast-cycle pressure swing adsorption technology is facilitating the developers of fuel cell systems to heighten the efficiency of their products. It has come to be known as a compact, cost effective gas purification solution to the industries developing hydrogen refueling infrastructure.
