Molecular Sieve 13X is the sodium form of the type X crystal and
has a much larger pore opening than the type A crystals. It
will adsorb molecules with a kinetic diameter of less than 9
Angstrom (0.9 nm) and exclude those larger.
It also has the highest theoretical capacity of the common
adsorbents and very good mass transfer rates. It can remove
impurities too large to fit into a type A crystal and is commonly
used to separate nitrogen from oxygen.
- Removal of CO2 and moisture from air (air pre-purification)
and other gases.
- Separation of enriched oxygen from air.
- Removal of mercaptans and hydrogen sulphide
from natural gas.
- Removal of mercaptans and hydrpogen sulphide from
hydrocarbon liquid streams (LPG, butane, propane etc.)
- Catalyst protection, removal of oxygenates from hydrocarbons
- Removal of n-chained compositions from aromatics.
- Production of bulk oxygen in PSA units .
- Production of medical oxygen in small scale oxygen
