Molecular
Sieve *3X 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.

Application
·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 (olefin streams).
·Removal of n-chained compositions from aromatics.
·Production of bulk
oxygen in PSA
units .
·Production of medical oxygen in small scale oxygen
concentrators
Regeneration:
Molecular sieve Type *3X can be regenerated by either heating
in the case of thermal swing processes; or by lowering the pressure
in the case of pressure swing processes.
To remove moisture from a *3X molecular sieve, a temperature of
******0°C is required. A properly regenerated molecular sieve can
give moisture dew points below ***0°C, or mercaptan or CO2 levels
below 2 ppmv.
The outlet concentrations on a pressure swing process will depend
on the gas present, and on the conditions of the process
Size
*3X - Zeolites are available in beads of **2 mm, (*0x*8 mesh)
**3 mm, (8x*2 mesh) , 2.**5 mm, (4x8 mesh) and as powder, and
in pellet 1.6, 3.2.
Attention
To avoid damp and pre-adsorption of organic before running,
or must to be reactivated.
