Dehydration for Various Gas Zeloite Molecular Sieves

Molecular Sieve
Molecular sieve is a material containing tiny pores of a precise and uniform size that is used as an adsorbent for gases and liquids. Molecules small enough to pass through the pores are absorbed while larger molecules are not. It is different from a common filter in that it operates on a molecular level.

For instance, a water molecule may be small enough to pass through while larger molecules are not. Because of this, they often function as a desiccant. Molecular sieve can absorb water up to 22% of its own weight.

We are proud to provide series of molecular sieves with strong ability of selective absorption, high mechanical strength, high abrasion resistance, and thermal stability. In accordance with your specific needs, specification of molecular sieve can be adjusted to match your application.


3A Molecular Sieve
The pore size of 3A molecular sieve is 3A. It does not adsorb any molecular larger than 3A.

According to the industrial application specialties, our products have the characters of higher adsorption speed, stronger crushing and anti-contaminative resistance, more cyclic times and longer work-span. All these advantages have made it come to be the most essential and necessary desiccant in the fields of the deep drying, refinery polymerization for cracked gasses (pyrolysis gas), ethylene, propylene and any other non-acidic gasses of liquids in petroleum and chemical industrials.

Drying of compressed air

Molecular sieves used for adsorption of water from air and liquids, as water molecules are both polar and very small. Molecular sieves will adsorb water molecules and other contaminants from liquids and gases down to very low levels - often just 1 part per million. The regeneration gases which are in common use are nitrogen, air, hydrogen and alkane. The regeneration gases quantity is 0.2-1.2m3/h. Kg or so, then heated to 200° C--350° C, the outlet temperature is 150° C or so, continuously heated for 3--4 hours, then put into the regeneration dry cool gases to cool to room temperature.

Package:
30kg or 25kg carton box, inside bag vacuum packing Or 120kg-150kg iron drum, inside bag vacuum packing Other package request by the customers.
Attention:
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
