3A molecular sieve has a pore size of 3A or 3 angstrom. Any molecule larger than 3A will not be able to be adsorbed. Mole Sieve is an alkali metal alumino-silicate, the potassium form of the type A crystal structure. 3 Angstrom is created when part of the sodium ions of the 4 Angstrom sieve are replaced by potassium ions. The sequence rate of adsorption rate is helium, neon, nitrogen and water. The advantages of our 3A mole sieve are consistently high adsorption speed, and higher contamination resistance, stronger crushing strength, increasing cyclic times which provide an extended product life. 3A Molecular Sieve is primarily for removing moisture from liquefied and gaseous materials. All these advantages have made it come to be the most essential and necessary desiccant in the fields of the deep drying, refinery, polymerization for cracked gases, ethylene, propylene and any other non-acidic gases or liquids in petroleum and chemical industrials.
The various specifications of Molecular Sieves are:
Form: Sphere (Balls) / Cylindrical Pellets Size: 1.5 - 3.5 mm. dia. / 1.5mm - 3.0 mm dia Bulk Density: 0.55 to 0.68 Kg/Liter Surface Area: 345 to 415 M2/Gm. Pore Volume: 0.40 to 0.50 CC/Gm. Adsorption Capacity (at 75 % RH) : 23-27 %. Attrition Loss: 0.02 -0.2 %.
It has become one of the most reliable desiccants for a variety of applications including: Refrigerant Drying Moisture removal in PU Plastic or Paint Natural Gas Drying Drying Cracked Gas Static drying of insulating glass units, whether air filled or gas-filled. Dehydration of highly polar compounds, such as methanol and ethanol. Dehydration of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien). Sweetening of Natural Gas
