Product Description
3A Molecular Sieves is an alkali metal aluminosilicate; 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 maximizes lifetime when dehydrating such molecules.
Application:
1. Separation of enriched oxygen from air.
2. Production of medical or bulk oxygen in PSA units.
3. Removal of co2 and moisture from air (air pre-purification)and other gases.
4. Catalyst protection , removal of oxygenates from hydrocarbons(olefin streams)
5. Removal of mercaptans and hydrogen sulphide from hydrocarbon liquid streams such as LPG, butane, propane etc.
