Regeneration
SNOWPEAK 3A 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 0.3-0.5kg/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°C, not use gases that produce explosive mixtures by contact with the adsorbent.
Gas removal: reduce the pressure
