Applications
Dehydration of many kinds of liquids (say Ethanol).
Dehydration of air.
Dehydration of Refrigerant.
Dehydration of natural gas or methane.
Dehydration of cracked gas, ethylene, ethyne, propylene or butadiene
Type 3A molecular Sieve is recommended for drying unsaturated hydrocarbons and highly polar compounds such as methanol and ethanol. The 3A structure is particularly effective in dehydrating the inner space of insulating glass windows as well as refrigerant gases.
Regeneration
Molecular Sieve 3A can be revived for reuse and the required factors for revival are temperature and pressure. To remove the adsorbed moisture and other materials, the revival condition shall be set up considering the features of target material and processing environment. The general revival temperature of Molecular Sieve 3A is about 200-350ºC.
