High purity industrial gases such as O2, N2, H2 and CO are manufactured through defined, highly specialized production processes. These processes include essential separation stages, where high quality Zeochem molecular sieves play an indispensible role, worldwide.

Cryogenic Air Separation Units (ASU)
In order to separate air cryogenically into oxygen and nitrogen the air must be treated in a front end purification process to separate out H2O, CO2, N2O and smaller hydrocarbon molecules.

Over the past 30 years Zeochem has developed a number of 13X and LSX molecular sieve products which allow tremendous performance advantages to be achieved.

High dynamic capacities for the removal of impurities Excellent adsorption and desorption kinetics (extremely long CO2 breakthrough times) High physical stability of the beaded product.

Products such as Zeochem Z10-02, Z10-02ND, Z10-08EP or Z10-10ND have proven in a large number of reference plants worldwide the outstanding performance in the pre- purification process.

Some of these products combine the ability to not only adsorb carbon dioxide and water but also nitrogen oxides and smaller hydrocarbons, molecules which increasingly must be removed from the air due to increased environmental requirements.
