  4A MOLECULAR SIEVE
  4A molecular sieve has a pore size of 4 A and adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, does not adsorb any molecule with a diameter greater than 4 A, including propane, and has a higher selectivity for water than any other molecule. Is one of the largest amount of molecular sieve industry.
  
  4A molecular sieve hot dry gas can be used as renewable gas, the purge of the regeneration gas, the molecular sieve removal of adsorbed water, renewable for repeated use. The degree of regeneration depends on the regeneration time and the temperature and humidity of the regeneration gas.
  
  Mainly used for natural gas and various chemical gases and liquids, refrigerants, pharmaceuticals, electronic materials and materials for deep drying, argon purification, methane, ethane, propane separation, paint, fuel, paint as a dehydrating agent.
