NM 3A molecular sieve has excellent adsorption performance and chemical stability, and can effectively remove moisture from methanol compounds. It can be used to produce methanol from natural gas, produce acetic acid, fuel, leather processing, cleaning and degreasing agents, produce formaldehyde, produce olefins, agricultural organic fertilizers, etc. fields are widely used.

NM 3A molecular sieve has extremely high affinity for moisture and can selectively adsorb water molecules. In the acetylene drying device, the acetylene passes through a drying tower equipped with a powder sieve, and the moisture in the acetylene is adsorbed onto the molecular sieve through physical adsorption, thereby achieving acetylene drying.

CNM 3A molecular sieve has the advantages of uniform pore size, large specific surface area, intact particles without fragmentation, long service life, stable quality, extremely high affinity for water, and can selectively adsorb water molecules. The moisture in isopropyl alcohol can be adsorbed onto the molecular sieve to achieve drying of isopropyl alcohol.

CNM 3A molecular sieve is widely used in the dehydration of chlorobenzene solvents. It has a specific pore size and can selectively adsorb molecules. When molecular sieve is added to chlorobenzene, 3A molecular sieve will adsorb water molecules in chlorobenzene, thereby reducing the water content in chlorobenzene. It has good water removal effect and is easy to operate. It is suitable for small and medium-sized water removal needs.

CNM 3A molecular sieve is widely used in the dehydration of toluene. Since toluene contains a small amount of water in industrial production applications, its purity and solubility will be reduced, affecting its properties and application effects. In addition, water-containing toluene can easily cause acid catalytic reactions, leading to a decrease in product quality. In order to remove trace amounts of moisture in toluene, 3A molecular sieves are used to achieve high-precision drying and dehydration through physical adsorption without producing pollutants and affecting the composition of raw materials.

CNM 3A molecular sieve is widely used in the dehydration and drying of butadiene. In chemical industry applications, because butadiene is a raw material participating in the reaction, it is mainly used in the synthesis of rubber; water content in the raw material will reduce the polymerization reaction speed, resulting in a decrease in product quality.

CNM 3A molecular sieve is widely used in the drying and dehydration of acetonitrile. Acetonitrile is a common organic solvent widely used in the fields of chemical synthesis, organic synthesis and analytical chemistry. However, industrial-grade acetonitrile often contains water, which can adversely affect the performance of certain reactions. Therefore, acetonitrile needs to be deeply dehydrated and dried.

CNM 4A molecular sieve is widely used in the dehydration of natural gas. Because the saturated moisture in natural gas feed gas may form hydrocarbon hydrates under certain conditions, it will block the pipelines and equipment of the liquefaction system, ultimately affecting natural gas production. In addition, for natural gas containing carbon dioxide and hydrogen sulfide, due to the action of moisture, they will form corrosive acid liquid, causing serious corrosion of equipment and pipelines. Therefore, the natural gas feed gas must be dehydrated.

CNM 4A molecular sieve is widely used in the drying and dehydration of ethyl acetate. Under normal pressure, the finished product of ethyl acetate contains a certain amount of water. In the process of purifying ethyl acetate, since the product water and ethanol can form binary and ternary azeotropes with ethyl acetate, they are also partially miscible at room temperature. This brings great difficulties to the purification of ethyl acetate. In order to obtain higher purity ethyl acetate, the ethyl acetate needs to be dried and dehydrated.
