3A Molecular Sieve Description

The pore size of molecular sieve is 3A^o. It does not adsorb any molecular larger than its pore size . According to the industrial application specialties, we endue our products with the characters of higher adsorption speed, stronger crushing and anti-contaminative resistance, more cyclic times and longer work-span is assured for our product. 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 industries.

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

Type 3A molecular Sieve is recommended for drying unsaturated hydrocarbons and highly polar compounds such as methanol and ethanol. The 3A structure is particularly effective in dehydrating the inner space of insulating glass windows as well as refrigerant gases.

Reactivation method :

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