The sodium-X crystal type with a much greater pore opening comparing to the A-type crystals. Adsorbing molecules with less than 10 Angstrom (1.0 nm) and it takes the highest theoretical capacity with very proper transfer rates. It can be employed to remove impurities which are too large to fit into A-type crystal and is commonly used for nitrogen-oxygen separation.

| Typical Application | a) CO2 and H2O removal from the air and/or other gases. b) Separation of enriched oxygen from the air. c) n-chained compositions removal from the aromatic components. d) R-SH and H2S elimination from the hydrocarbon streams ( such as LPG and butane) e) Catalysts protection, oxygenate removal from hydrocarbons (olefin streams). f) Production of bulk oxygen in PSA units. |
