The pore size of 3A molecular sieve is 3 Å . It does not absorb any
molecular larger than 3 Å. It is an alkali metal alumino-silicate,
the potassium form of the type A crystal structure. 3 Angstrom, is
obtained when part of the sodium ions of the 4 Angstrom sieve are
replaced by potassium ions. Will absorb, in sequence of adsorption
rate, helium, neon, nitrogen and water.
According to the industrial
application specialties, we endue our products with the characters
of higher absorption speed, stronger crushing and
anti-contaminative resistance, more cyclic times and longer
work-span. 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.
Application
Molecular Sieve 3A is mainly used to
remove moisture and can be applied to liquefied and gaseous
materials on the whole. The main uses are as follows.
1) Drying of refrigerants (e.g. R*2, R**4a etc)
2) Removing moisture in paint and PU Plastic
3) Drying of natural gas
4) Cracked Gas Drying.
5) Static dehydration of insulating glass units, whether air filled
or gas-filled.
6) Drying of highly polar compounds, such as methanol and
ethanol.
7) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene,
butadien).
8) Drying of olefins drying, ethanol, etc.
9)Dehydration of many kinds of liquids (say ethanol)
air, refrigerant , natural gas or methane , cracked gas, ethylene,
ethyne, propylene or butadiene .
