4A molecular sieve is one of the most consumable molecular sieves used in the industry, its selective adsorption to water is higher than any other molecule. Chemequip 4A molecular sieve adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene and other molecules with diameters not more than 4 angstroms. Usually used for gas and liquid drying but also for refining and purification of certain gases or liquids, such as the preparation of argon
Chemequip 4A molecular sieve can be purged and regenerated by increasing the temperature, regeneration (dehydration) degree depends on the humidity and temperature of the purging gas.
Water Removal: Heat dry gas such as nitrogen, air, hydrogen, saturated hydrogen carbide to 150-320℃, then pass it into the molecular sieve bed under the pressure of 0.3-0.5 kg/m2 for 3-4 hours, and then pass the dry cold gas into the adsorber for 2-3 hours, isolate the air and cool it to room temperature.
Organic Removal: Replace the adsorbent from the molecular sieve by water vapor, and then heat. Or pass into hot vapor or inert gas at the in 200-350℃, not use gases that produce explosive mixtures by contact with the adsorbent.
Gas Removal: Reduce the pressure
