4A Molecular Sieve for dehumidification of oil gas
Product Description
4A molecular sieve should be used in confined gas or liquid system as a static desiccant for static dehydration in the freeze drying agents, drug packaging, electronics components, chemicals, or in the paint and plastic systems as a dehydrating agent. 4A molecular sieve can also be used in industry for drying saturated hydrocarbon materials.
When material can be adsorbed by3A molecular sieve elements, can also be adsorbed by 4A type.
Regeneration:
4A molecular sieve can be regenerated under condition of raising the temperature or vacuumized .
