molecular sieve Natural Gas Drying
Product Description:
Molecular sieve Natural Gas Drying
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. Typical Chemical Formula
Na2O Al2O3 2.0SiO2 4.5H2O
SiO2: Al2O3 ≈2

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
4) Packed in small bags, it may be used simply as a packaging desiccant
Regeneration
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.
To remove moisture from a 4A molecular sieve, a temperature of 250-280°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C.
4A - Zeolites are available in beads of 1-2 mm, (10x18 mesh) 2-3 mm, (8x12 mesh) , 2.5-5 mm, (4x8 mesh) and as powder, in pellet 1.6", 3.2". Attention
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
