3A Molecular Sieve Dehydrates Ethanol Solvent

As one of the most professional manufacturers of famous brands' 3A Molecular Sieve, we warmly welcome you to buy the 3a molecular sieve dehydrates ethanol solvent in stock from us. Low price and excellent after-sale service will be offered.

Product Introduction: Chemxin 3A Molecular Sieve
Chemxin's 3A molecular sieve is a synthetic zeolite adsorbent with a pore size of 3 Angstroms (Å). It features a uniform pore structure and a very high specific surface area. It is mainly used to adsorb water molecules - only molecules smaller than the pore diameter (such as water) can enter, while larger molecules like ethanol are excluded.

Key characteristics of Chemxin 3A molecular sieve:
High water adsorption capacity( static water adsorption＞21%)
Low dust generation
High crush strength
Regenerable for repeated use
Does not swell or disintegrate during liquid-phase dehydration

Chemxin 3A molecular sieves are manufactured under strict quality control standards, ensuring batch-to-batch consistency and a long service life in industrial ethanol drying processes.

Working Principle: How 3A Molecular Sieve Dehydrates Ethanol Solvent
Pore Size Selectivity
3A molecular sieve pore size: approximately 3 Ångströms (0.3 nm)

Water molecule kinetic diameter: approximately 2.8 Å
Ethanol molecule kinetic diameter: approximately 4.4 Å
Adsorption of Water Molecules
When the ethanol solvent containing water impurities flows through a fixed bed of molecular sieve 3A, water molecules diffuse into the sieve pores and are physically adsorbed onto the internal surface through strong polarity and electrostatic forces.

Exclusion of Ethanol Molecules
Ethanol molecules, being larger than 3 Å, cannot enter the pores. They flow around the sieve particles without being adsorbed.

Effluent Purity
The treated ethanol solvent has significantly reduced water content, and even lower levels can be achieved depending on the process design.

Regeneration
After saturation, the adsorbed water can be desorbed from the molecular sieve by heating (typically 200–300°C) or by pressure swing. This allows the molecular sieve to be reused repeatedly in cyclic dehydration processes.

Conclusion
For any company seeking a proven adsorbent for ethanol drying, Chemxin's 3A molecular sieve offers a dependable, high-performance solution.
