3A IG Molecular Sieves

Molecular Sieve Sieve 3A is an alkali alumino silicate. It is the potassium form of the molecular sieve type A and has an effective pore opening of about 3 angstroms (0.3 nm).
Typical Chemical Formula : 0.45 K₂O – 0.55Na₂O Al₂O₃ -2SiO₂ - nH₂O
Applications :
Molecular Sieves 3A is commonly used for the following applications :

• Static (non regenerative) removal of H₂O from air, organic vapour & gas like COS  filled insulating glass units and from solvents & fluids like 2-Propanol, Acetone, Acetonitrile, Acrylonitrile, Dimethyl Sulfoxide, Sulphur Hexafluoride, refrigerant gases etc
• Molecular Sieve 3A will adsorb molecules with a kinetic diameter of less than 0.3 nm and exclude those larger.

Type : 3A IG Grade is also available in Standard balls form.
Regeneration : Molecular Sieve 3A can be regenerated by evacuating or purging, usually at elevated temperatures. The purge gas temperature must be sufficiently high to bring the molecular sieve to a level of 1800C to 250^oC, but not exceeding 300^oC. Higher temperatures may cause physical degradation of the molecular sieve structure. When used to dry streams containing olefins, a purge at lower temperature is advised to prevent polymerization during regeneration. The degree of regeneration depends on the temperature, pressure and humidity of purge gas, and is a strong factor in affecting product purity. It is possible to dry fluids to less than 0.1 ppm H₂O, if adequately regenerated.
Shipping Information : Molecular Sieve 3A Grade is available in 150 Kg Air Tight Steel Drum Sealed with inner Liner (Polyethylene bags) for Extra Protection.
