Typical Application
a) 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 mini missing COS formation. Light mercaptans are also adsorbed.
b) Separation of normal- and iso paraffin’s.
c) Production of high purity N2, O2, H2 and inert gases from mixed gas streams
d) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
