    Description
    Molecular Sieve type 5A is an alkali alumino-silicate; it is the calcium form of the Type A crystal structure. Type 5A has an effective pore opening of 5 angstroms (0.5nm). It will adsorb molecules with a kinetic diameter of less than 5 Angstrom and exclude those larger. 
    It is especially suitable for PSA generator applications where it may be used for the separation of normal- and iso- paraffins (C4 to C6 species), in PSA H2 purification and in oxygen concentrators.

    Application - The strong ionic forces of the divalent calcium ion make it an excellent adsorbent to remove water, CO2, H2S from sour natural gas streams, while minimising COS formation. Light mercaptans are also adsorbed.
    - It is also used for the separation of normal and isoparaffins.
    - Production of high purity N2, O2, H2 and inert gases from mixed gas streams.
