3A Molecular Sieve

The pore size of 3A molecular sieve is 3Ǻ. It does not adsorb any molecular larger than
3 Ǻ. According to the industrial application specialties. We endue our products with the characters of higher adsorption speed, stronger crushing and anticontaminative 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 gases, ethylene, propylene and any other non-acidic gases or liquids in petroleum and chemical industrial.

*This is the typical parameter of this kind, different applications require different parameter, please contact us for detail.


Reactivation Method:

Insufflate the sieve bed with vapor to exchange the organics out to avoid char formation at first, and then reactivate the molecular sieve with common method. For further detail, please adibe our latest instructions.

Typical applications:

  • Dehydration of many kinds of liquids (say ethanol)
  • Dehydration of air.
  • Dehydration of refrigerant.
  • Dehydration of natural gas or methane.
  • Dehydration of cracked gas, ethylene, ethyne, propylene or butadiene.

Packing

25 kg. cartoon drum, 140 kg. steel drum.

Attention:

To avoid damp and pre-adsorption of organics before running or must to be reactivated.
