Molecular Sieve 3A

DESCRIPTION:

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, ethylene, propylene and any other non-acidic gasses of liquids in petroleum and chemical industrials.

Formula: 0.4K2O . 0.6Na2O . Al2O3 . 2SiO2 . 4.5 H2O                    (SiO2 : Al2O3 ≈2)

APPLICATION:

1) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien)

2) Cracked gas drying

3) Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.

4) Drying of highly polar compounds, such as methanol and ethanol

5) Drying of liquid alcohol

6) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.

7) Drying of refrigerants
