50 Tons of 3A Molecular Sieve for Ethanol Solvent Dehydration Exported to Russia
Industrial Ethanol Solvent Dehydration Solution
In the field of industrial ethanol solvent processing, moisture control is critical. Excess water in ethanol solvents can reduce reaction efficiency, damage equipment, and compromise final product quality. A widely adopted and highly effective solution is the use of high-performance 3A molecular sieve adsorbents.
This case study highlights a successful cooperation between Xintao (a professional molecular sieve manufacturer with over 20 years of experience) and a Russian client who required an efficient ethanol solvent dehydration solution.
Order Overview
Initial Inquiry (November 2025)
A Russian company engaged in industrial ethanol solvent dehydration first contacted Xintao in November 2025. The client showed strong interest in molecular sieve products and sought a reliable supplier.
Technical Communication & Solution Proposal
Xintao’s sales team responded promptly and conducted in-depth technical discussions. Based on the client’s specific requirement — removing water from ethanol solvents — Xintao provided a professional molecular sieve selection solution along with a detailed quotation.
First Order (January 2026)
After rigorous evaluation, the client placed an initial order for 25 tons of 3-5 mm 3A molecular sieve desiccant beads in January 2026.
Positive Feedback & Successful Operation
After putting the product into use, the Xintao team continuously monitored performance. The client reported:
- Stable operation of the Xintao 3A zeolite molecular sieve adsorbent
- Excellent water removal efficiency
- Reliable and consistent ethanol solvent dehydration performance
The first cooperation was successfully completed, and Xintao earned the client’s high trust.
Repeat Order (May 2026)
Based on the outstanding performance, the client recently placed a second order — another 25 tons of the same 3-5 mm 3A zeolite from Xintao.
Product Introduction: Xintao 3A Molecular Sieve
Xintao’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 Xintao 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
Xintao 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
This successful export of 50 tons of Xintao molecular sieve 3A zeolite to Russia fully demonstrates the product’s reliability in real-world ethanol solvent dehydration applications. From the initial inquiry to the repeat order, Xintao’s technical support, product quality, and customer-first service helped build deep trust with the client.
For any company seeking a proven adsorbent for ethanol drying, Xintao’s 3A molecular sieve offers a dependable, high-performance solution.
