Air separation units (ASUs) are foundational to many industrial processes, providing essential gases like oxygen and nitrogen. The efficiency and purity of these gases are heavily dependent on the quality of the adsorbents used within the ASU's purification stages. NINGBO INNO PHARMCHEM CO.,LTD. highlights the critical role of 13X molecular sieves in optimizing these processes, particularly in removing water and carbon dioxide to achieve high-purity oxygen streams.

At the heart of an air separation unit is the pre-purification stage, where ambient air is cleaned before cryogenic distillation. This stage is responsible for removing moisture (water vapor) and carbon dioxide (CO2). Both are detrimental to the cryogenic process; moisture can freeze and block vital equipment, while CO2 can solidify and foul heat exchangers. Zeolite molecular sieves, specifically the 13X type, are exceptionally well-suited for this task due to their large pore openings (approximately 10 angstroms) and high adsorption capacity for both water and CO2. The selective adsorption capability ensures that while these impurities are efficiently removed, the primary components of air – nitrogen and oxygen – pass through unimpeded.

NINGBO INNO PHARMCHEM CO.,LTD. supplies high-performance 13X molecular sieves that are designed for robust operation within ASUs. These adsorbents offer a superior combination of adsorption capacity, mechanical strength, and thermal stability, enabling them to withstand the thousands of regeneration cycles required in continuous ASU operation. The consistent performance of these molecular sieves directly translates to higher product yields and greater operational reliability for air separation facilities. Considering the price of molecular sieves is important, but the long-term operational benefits often justify the investment in premium products.

The process typically involves passing compressed air through beds packed with the 13X molecular sieve. As the air flows through, the sieve material traps the water and CO2 molecules. Once the sieve becomes saturated, it is regenerated by heating and purging, releasing the adsorbed impurities. This cyclical process is fundamental to achieving the extremely low dew points and CO2 concentrations required for efficient cryogenic distillation. By employing high-quality 13X molecular sieves, industries can ensure the production of high-purity oxygen and nitrogen, vital for applications ranging from medical support to the steel industry. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing the essential materials that drive these critical industrial operations forward.
