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 (0.5 nm). It will adsorb
molecules with a kinetic diameter of less than 5 Angstrom and
exclude those larger.
Application
- The strong ionic forces of the divalent calcium ion makes 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 iso
paraffins.
- Production of high purity N2, O2, H2 and inert gases from
mixed gas streams.
