NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to advancing industrial processes through high-performance chemical solutions. Among our specialized offerings, the 13X molecular sieve stands out for its critical role in cryogenic air separation and various gas purification applications. Understanding the importance of precise contaminant removal is key to optimizing these complex industrial operations.

Cryogenic air separation is a sophisticated process used to produce high-purity oxygen, nitrogen, and argon from ambient air. A fundamental challenge in this process is the presence of water vapor and carbon dioxide, which can freeze at the extremely low temperatures required for liquefaction. This freezing can lead to blockages and plant shutdowns, incurring significant costs and downtime. This is where the exceptional adsorption capabilities of the 13X molecular sieve become invaluable.

The 13X molecular sieve, a synthetic zeolite with a uniform pore opening of approximately 10 Angstroms, is specifically engineered to capture molecules larger than 9 Angstroms. This includes CO2 and water vapor, which are the primary contaminants targeted in air separation. By effectively adsorbing these impurities in a pre-purification unit (PPU), the 13X molecular sieve prevents them from entering the cryogenic distillation columns. This selective adsorption not only ensures the integrity of the air separation process but also dramatically improves the purity of the final products.

One of the key advantages of using the 13X molecular sieve is its high capacity for carbon dioxide adsorption. This characteristic is particularly important because CO2 is a significant impurity that needs to be meticulously removed. Coupled with its efficiency in water removal, the 13X sieve ensures that the air entering the cold box is exceptionally dry and free from CO2. Furthermore, its relatively low regeneration temperature means that the sieve can be efficiently restored to its active state with less energy input, contributing to overall cost savings and a more sustainable operation. The long service life of this adsorbent also means fewer replacements are needed, further enhancing its economic viability.

Beyond air separation, the 13X molecular sieve finds extensive use in other gas purification applications. It is employed for the drying and desulfurization of natural gas, liquefied petroleum gas (LPG), and various liquid hydrocarbons. In these applications, it selectively removes sulfur compounds and moisture, improving fuel quality and preventing corrosion in pipelines and equipment. Its versatility also extends to being used as a catalyst carrier in certain chemical reactions, leveraging its stable structure and high surface area.
