Insulating Glass Desiccant Pure Molecular Sieve 3A

Introduction
ABSORBKING Molecular Sieve type 3A is an alkali metal alumino-silicate; It is the potassium form of the type A crystal structure. Type 3A has an effective pore opening of about 3 angstroms (0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers; And this maximises lifetime when dehydrating such molecules.

Typical Application
Drying of unsaturated hydrocarbons (e. G. Ethylene, propylene, butadien)
Cracked Gas Drying
Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.
Drying of highly polar compounds, such as methanol and ethanol
Drying of liquid alcohol
Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
Drying of refrigerants
Regeneration
Absorb King molecular sieve Type 3A 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, 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.
Size
3A - Zeolites 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" Attention

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.
