Zeolite Molecular Sieve 4A for Natural Gas Dehydration Desiccant
Product Description
Molecular sieve 4A is an alkali alumino silicate; it is the sodium form of the Type A crystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm). VODA 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 4) Packed in small bags, it may be used simply as a packaging desiccant
Size 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, and in pellet 1.6", 3.2".
Attention To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
