Introduction - Molecular Sieve Adsorbents • Strong adsorptive force to remove many gas or liquid impurities to very low levels (ppm or less) • Differ from other adsorbents in the form of their isotherms which have a high adsorption capacity for relatively low concentrations of the adsorbate
Molecular sieves are loaded in vertical adsorbers. The gas to be dried goes through the adsorbers, and water is captured along the way. Within a few hours (12 to 36 hours depending on the size of the adsorption unit), a given bed is saturated with water and it has to be regenerated.
