Introduction:
Zeolite molecular sieve 3A is an alkali metal alumino silicate; it is the potassium form of the Type A crystal structure. Type 3A has an effective pore opening of 3 angstroms (0.3 nm). It is large enough to allow in moisure, but excludes moleculars such as unsatureated hydrocarbons which can potentially form polymers: and this maximises lifetime when dehydrating such molecules.
Typical Chemical Formula:
0.45k2O ·0.55Na2O·Al2O3 ·2.SiO2· 4.5H2O
Application:
1) Drying of unsatureated hydrocarbons(e.g. ethylene, propylene, butadien)
2) Cracked Gas Drying
3) Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required.
4) Drying of highly polar compounds, such as methanol and ethanol
5)Drying of liquid alcohol
6)Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.
7)Drying of refrigerants

Packing:
By carton box, each box 30kg or 25kg, inside airtight bag.
Or 40kg/sealed iron drum, inside airtight bag.
Regeneration:
Molecular sieve Type 3A 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 3A molecular sieve, a temperature of 200-230°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C.The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process
Size:
3A - 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.
