Product Description
Specifications
adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.Product Description
Pingxiang Zongying packing Co., Ltd is over 10 years BV and SGS certified manufactuer. Products have been supplying to over 50 countries with good feedback on quality.
4 A Molecular sieve is suitable for the drying of gas and liquid, with a aperture of about 4 angstroms. It adsorbs such gases as H2O, NH3, H2S, CO2, SO2, CO, methyl chloride(H3CCl), methyl bromide(H3CBr), acetylene(H2C2), ethane(H6C2), ethene(H4C2), propylene(H6C3). It is widely used in the drying of oil field associated gas and natural gas. It is also used to prevent the condensation of vacuum glass.
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.
The pore size for 4A molecular sieve is 4A. It is mainly used to adsorb water, methanol, ethanol, sulfureted hydrogen, carbon dioxide, ethylene, propylene, does not adsorb any larger molecular than 4A, and often used as desiccant in industrials.
FORMULA: Na2O Al2O3 2.0SiO2 4.5H2O
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 250-280º C is required. A properly regenerated molecular sieve can give moisture dew points below -100º C.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process
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 1.6mm, 3.2mm.
ATTENTION
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
