NINGBO INNO PHARMCHEM CO.,LTD. is committed to advancing the efficiency and purity in industrial processes. Among our specialized offerings, 13X molecular sieves stand out for their critical role in complex separation and purification applications, particularly within the demanding field of cryogenic air separation.

The process of cryogenic air separation involves cooling air to extremely low temperatures to liquefy it, followed by distillation to separate its components like oxygen, nitrogen, and argon. A vital preliminary step is the purification of the incoming air stream. This is where 13X molecular sieves, with their remarkable adsorption capabilities, become indispensable. They are specifically designed to capture impurities such as water vapor (H2O) and carbon dioxide (CO2). The presence of these impurities in the cryogenic section can lead to severe issues, including freezing and blockage of heat exchangers and distillation columns, ultimately causing plant shutdowns and significant operational losses. Our 13X molecular sieves effectively mitigate these risks, ensuring a smooth and continuous operation.

The efficacy of 13X molecular sieves stems from their unique crystalline structure, specifically their large pore openings, typically around 10 Angstroms (Å). This size allows them to selectively adsorb molecules smaller than this diameter while excluding larger ones. This precise molecular sieving action is what makes them so effective in removing CO2 and H2O from the air feed. Furthermore, they exhibit a high adsorption capacity, meaning a significant amount of impurities can be captured before regeneration is required. This translates to longer operational cycles and reduced downtime, a key factor in the economic viability of air separation plants.

The adsorption mechanism of 13X molecular sieves is primarily based on physical adsorption, driven by the electrostatic interactions between the polar molecules of the impurities and the internal surface of the zeolite. The high surface area within the sieve's structure provides numerous adsorption sites. Once saturated, these sieves can be readily regenerated, typically through temperature or pressure swing, allowing for their reuse over many cycles. This regenerability not only makes them environmentally friendly but also highly cost-effective for continuous industrial operations. Understanding the importance of molecular sieve regeneration process is key to maximizing their lifespan and performance.
