4A molecular sieve is one of the most consumable molecular sieves used in industry, its selective adsorption of water is higher than any other molecule. WANLI 4A molecular sieve adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene and other molecules with diameters no 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.

3A molecular sieve is an alkali metal aluminosilicate, also called KA molecular sieve or 3A zeolite molecular sieve, mainly used to adsorb water. WANLI 3A molecular sieve has faster adsorption speed, more regeneration times, higher crushing strength and anti-pollution ability, which can improve utilization efficiency and prolong service life. It's really the preferred desiccant necessary for deep drying, refining and polymerization of gas and liquid in petroleum and chemical industry.

WANLI 13XAPG molecular sieve is dedicated to air cryo-separation industry, applicable to any size of air cryo- separation devices. The adsorption capacity of carbon dioxide and moisture was futher improved, to avoid frozen tower phenomenon in the distillation process. Good kinetic characteristics can maximize the adsorption effect of the existing adsorption bed, and reduce the size of the newly designed adsorption bed, thus decrease energy consumption.
