*-) What is 3A Molecular Sieve
Molecular Sieve 3A is an alikali metal alumino-silicate;it is the
potassium form of the type A crystal structure.Type 3A has an
effective pore opening of about 3 angstroms(0.3nm).This is large
enough to allow in moisture,but excludes molecules such as
unsaturated hydrocarbons which can potentially form polymers;and
this maximises lifetime when dehydrating such molecules.
*-) 3A Molecular Sieve Applications:
2.1.Petroleum and Chemical Industry
3 molecular sieves do not adsorb chemicals whose molecular
diameters are larger than 3 . The characteristics of these
molecular sieves include fast adsorption speed, frequent
regeneration ability, good crushing resistance and pollution
resistance. These features can improve both the efficiency and
lifetime of the . 3 molecular sieves are the necessary desiccant in
petroleum and chemical industries for refining oil, polymerization,
and chemical gas-liquid depth drying
2.2.Dessicants
3 molecular sieves are used to dry a range of materials, such as
ethanol, air, refrigerants, natural gas and unsaturated
hydrocarbons. The latter include cracking gas, acetylene, ethylene,
propylene and butadiene.
