Air separation units (ASUs) are critical facilities that produce high-purity oxygen, nitrogen, and argon for a vast array of industries, from healthcare and electronics to metallurgy and food processing. A key stage in the efficient operation of ASUs involves the removal of impurities, primarily moisture and carbon dioxide, from the incoming feed air. Activated alumina is the material of choice for this crucial task, owing to its exceptional adsorption capabilities. NINGBO INNO PHARMCHEM CO.,LTD. provides top-tier activated alumina, essential for achieving the stringent purity requirements in air separation.

The process of cryogenic air separation involves liquefying air and then separating its components based on their boiling points. However, moisture and carbon dioxide must be removed before liquefaction, as they can freeze at cryogenic temperatures, leading to blockages, reduced efficiency, and potential damage to the equipment. Activated alumina, with its high affinity for water molecules and carbon dioxide, acts as a highly effective adsorbent in pre-purification systems. Its ability to achieve very low dew points is critical for the entire process. The role of activated alumina desiccant in this context cannot be overstated.

Our activated alumina balls are specifically designed to offer high adsorption capacity for both moisture and CO2. The large surface area and porous structure of the activated alumina provide numerous active sites for these impurities to bind to. The uniformity of the spherical particles ensures efficient packing in adsorbent vessels, promoting optimal contact between the feed air and the activated alumina. This leads to a thorough purification of the air stream, guaranteeing the high purity of the final products like oxygen and nitrogen. The importance of high surface area activated alumina is directly linked to its efficiency in these purification trains.

Furthermore, activated alumina is regenerable, meaning it can be heated to release the adsorbed moisture and carbon dioxide, allowing it to be reused multiple times. This regenerability makes it an economical and sustainable choice for ASUs. The thermal stability and mechanical strength of our activated alumina products ensure that they withstand numerous regeneration cycles without significant loss of performance. When considering activated alumina for gas drying, its reusability is a significant advantage.
