zeolite 3a price   zeolite powder  

type 3A Molecular Sieve Dessicant has a pore size of 3A or 3 angstrom. Any molecule larger than 3A will not be able to be adsorbed. Mole Sieve is an alkali metal alumino-silicate, the potassium form of the type A crystal structure. 3 Angstrom is created when part of the sodium ions of the 4 Angstrom sieve are replaced by potassium ions. The sequence rate of adsorption rate is helium, neon, nitrogen and water.

The advantages of our 3A molecular sieves desiccant from manufacturer
are consistently high adsorption speed, and higher contamination resistance, stronger crushing strength, increasing cyclic times which provide an extended product life. 3A Molecular Sieve desiccant is primarily for removing moisture from liquefied and gaseous materials.

It has become one of the most reliable desiccants for a variety of applications including:

• Refrigerant Drying

• Moisture removal in PU Plastic or Paint

• Natural Gas Drying

• Drying Cracked Gas

• Static drying of insulating glass units, whether air filled or gas-filled.

• Dehydration of highly polar compounds, such as methanol and ethanol.

• Dehydration of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien).

Regeneration

3A Molecular Sieve desiccant regenerated and reused. To regenerate the sieve you need to remove the adsorbed moisture and other materials. To regenerate heat to 250°C.

Storage

Keep 3A molecular sieves desiccant from anufacturer in an air tight container until ready for use to avoid unintended moisture adsorption.

Molecular Sieve Dessicant Technical Parameter

Molecular Sieve Dessicant Typical 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

Molecular Sieve Dessicant Regeneration
Absorbking 3A Zeolite Molecular sieve desiccant can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes.
To remove moisture from a 3A molecular sieve desiccant, a temperature of 200-230°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.

the Size of Molecular Sieve Dessicant
3A molecular sieves from anufacturer are available in beads of 1-2 mm, (10x18 mesh) 2-3 mm, (8x12 mesh) , 2.5-5 mm, (4x8 mesh) and as powder, and in pellet 1.6, 3.2.
