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."
4A molecular sieves can adsorb molecules with a diameter of not more than 4A, such as water, CH3OH, hydrogen sulfide, carbon dioxide, ethylene, C3H6, etc., and are mainly used for drying LNG and a mixture of gases and liquids.

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.
