Zeolite molecular sieves have the structure and characteristics of crystals, the surface is a solid skeleton, and the internal
holes have the function of adsorbing molecules. There are pores connected to each other, and molecules pass through the pores
channels. Due to the crystalline nature of the pores, the pore size distribution of molecular sieves is very uniform. Molecular
sieves selectively adsorb molecules according to the size of the holes in their crystal, that is, they adsorb molecules of a
certain size and repel molecules of larger substances, so they are figuratively called "molecular sieves."
3A molecular sieves are usually formed by the exchange of potassium ions to 4A molecular sieves instead of sodium ions. They are
mainly used for the adsorption of water molecules and are suitable for the drying of gases and liquids, such as LNG, petroleum,
ethanol, etc.
3A Molecular Sieve Application Fields
1) Drying of various liquids (such as ethanol)
2) Drying of air
3) Drying of refrigerant
4) Drying of LNG and CH4 gas
5) Drying of unsaturated hydrocarbons and cracking gas, ethylene, acetylene, C3H6, and butadiene

Storage
Prevent the molecular sieves from exposing directly to the damping environment and any absorption of water or organic substance before it's used, otherwise it must be regenerated.
All Chemequip molecular sieves can be regenerated by temperature or pressure swing.
Delivery
For small quantity order < 100kg, 10 days after purchased contract is efficient.
For big quantity order > 500kg, 15 days after purchased contract is efficient.
