Air Separation Units (ASUs) are the backbone of industries requiring high-purity gases like oxygen and nitrogen. The efficiency and purity achieved in these processes are heavily dependent on the quality of the adsorbents used to remove critical contaminants like water (H2O) and carbon dioxide (CO2) from the air stream. Among the various molecular sieves available, the 13X Molecular Sieve is exceptionally well-suited for this demanding application. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated manufacturer and supplier, plays a crucial role in providing these essential materials to the global market.

The Challenge in Air Separation: Contaminants to Remove

Ambient air, while abundant, contains several components that must be meticulously removed before liquefaction and subsequent separation into its constituent gases. The primary contaminants are:

  • Water Vapor (H2O): Moisture can freeze at cryogenic temperatures, leading to ice formation that can block heat exchangers and instrument lines, potentially causing system damage and operational failures.
  • Carbon Dioxide (CO2): CO2 also freezes at cryogenic temperatures, albeit at a higher temperature than ice. Its solidification can lead to similar blockages and performance degradation in ASUs. Furthermore, CO2 can react with alkaline components, leading to unwanted by-products.

Effective removal of these contaminants to extremely low levels (parts per million) is critical for the safe and efficient operation of ASUs. This is where the unique properties of molecular sieves become invaluable.

Why 13X Molecular Sieve is Ideal for ASUs

The 13X Molecular Sieve, with its 10 angstrom pore size, is specifically designed for the simultaneous adsorption of both water and carbon dioxide. Unlike other molecular sieves that might be selective for only one of these contaminants, 13X offers a dual action that simplifies the purification process.

  • Co-Adsorption Capability: Its larger pore opening allows it to efficiently adsorb both H2O and CO2 molecules, making it highly effective in pre-purification stages of ASUs.
  • High Adsorption Capacity: It provides a significant capacity for both water and carbon dioxide, ensuring that even at high feed rates, the air stream is purified to the required low levels. This translates to better performance and less frequent regeneration cycles.
  • Selectivity: While it adsorbs H2O and CO2, it largely excludes nitrogen (N2) and oxygen (O2), which are the desired products. This selectivity is key to achieving high gas purities.
  • Thermal Stability: 13X Molecular Sieves are robust and can withstand the thermal regeneration cycles necessary to restore their adsorptive capacity, ensuring a long service life.
