Molecular Sieve 4A*-Natural Gas Drying 0.5 mm
is an alkali alumino silicate; it is the sodium form of the Type A crystal structure. XINGFENG type 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger. Such adsorbable molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxyde and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.

Application
1) Drying and removing of CO2 from natural gas, LPG, air, inert and
athmospheric gases, etc
2) Removal of hydrocarbons, ammonia and methanol from gas
streams (ammonia syn gas treating)
3) Special types are used in the air break units of buses, trucks
and locomotives
Regeneration
1)Molecular sieve Type 4A 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.
2)To remove moisture from a 4A molecular sieve, a temperature of
******0°C is required. A properly regenerated molecular sieve can
give moisture dew points below ***0°C.
3)The outlet concentrations on a pressure swing process will depend
on the gas present,
Size
4A - 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".
