Gas Drying Adsorb Water Molecular Sieve 3A Regenerated by Heat

Product Detail

gas drying adsorb water molecular sieve 3a regenerated by heat.

Chemxin Molecular Sieve type 3A, Its effective aperture is 3 eh, mainly used for absorbed water(the diameter of water molecules is about 2.8 eh), not adsorb any molecular diameter greater than the water and thus play a role in screening, With the adsorption rate was fast, regeneration frequency ,more crash-resistant, high strength and Strong anti-pollution ability,  adsorption efficiency and long life for high-end sector of choice for high-precision dry moisture products, Control of the cavity insulating glass has long maintained at the dew point below -60 .

2. Regeneration:

Chemxin 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.




3. Size: 

3A - Zeolite 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 1.6mm, 3.2mm.




4. Attention:
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
