NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing advanced materials that drive efficiency in critical industrial processes. Among these, Molecular Sieve 13X stands out for its indispensable role in Air Separation Units (ASUs). The ability to effectively purify air is fundamental to producing high-purity nitrogen and oxygen, essential gases for numerous industries.

Air, a mixture primarily of nitrogen and oxygen, also contains trace amounts of water (H2O) and carbon dioxide (CO2). In cryogenic air separation processes, these impurities must be removed before the air enters the distillation columns. If left untreated, water can freeze and form ice crystals, blocking cryogenic heat exchangers and valves, a phenomenon known as the 'freezing tower' issue. Carbon dioxide can also solidify, causing similar blockages and reducing process efficiency.

This is where Molecular Sieve 13X excels. With its 10 Angstrom pore size, it has a high adsorption capacity for both water and carbon dioxide. The designation '13X' specifically refers to its ability to adsorb molecules up to 10 Angstroms, which includes H2O and CO2. This makes it a perfect candidate for the pre-purification stage in ASUs. The 13X molecular sieve for air separation purification ensures that the feed gas entering the cryogenic distillation system is free from these problematic impurities.

The process typically involves passing compressed air through beds of Molecular Sieve 13X. The sieve selectively adsorbs the water and carbon dioxide molecules, allowing the purified nitrogen and oxygen to pass through. The sieve's high adsorption capacity means that a significant amount of impurities can be removed, ensuring the clean operation of the ASU. Furthermore, the 13X molecular sieve CO2 adsorption capacity is particularly noteworthy, allowing for very low CO2 concentrations in the purified air.

When the sieve becomes saturated, it can be regenerated by heating, allowing for its reuse. This regenerability is a key factor in the economic viability of ASUs. NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality 13X Molecular Sieves that are optimized for these demanding applications, ensuring reliable performance and extended service life.

Beyond air separation, the versatility of Molecular Sieve 13X is also seen in its applications for drying and desulfurization of natural gas and its use as a 13X molecular sieve catalyst carrier. However, its contribution to the efficiency and reliability of air separation remains one of its most critical industrial functions.
