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.

Lithium battery electrolyte is a liquid composed of organic solvents, inorganic salts and additives. When the water content in the electrolyte is too much, it not only increases the internal resistance of the electrolyte and reduces the capacity and cycle life of the battery, but may also cause battery short circuit, spontaneous combustion, explosion and other serious consequences. Therefore, the lithium battery electrolyte needs to be dehydrated and dried.

Since raw natural gas contains a little moisture, hydrates will form when the ambient temperature is equal to or lower than 0°C, blocking pipelines. In addition, natural gas contains carbon dioxide, hydrogen sulfide and other gases, which can easily form acid with water, causing damage to equipment and pipelines. corrosion. Hydrates will be generated during decompression and cooling under storage pressure, which will block pipes, gas bottle nozzles, charging nozzles, etc.,

Molecular sieves have a wide range of application prospects and have been called “one of the new materials of the 21st century”. There are many types of molecular sieves that can adsorb different molecules. It has a microporous structure with uniform gaps inside like a sieve, which can screen and adsorb different molecules

CNM 4A molecular sieve has the characteristics of selective adsorption capacity, large total adsorption capacity, high adsorption efficiency, acid and alkali resistance, and long service life.

CNM-4A molecular sieve is widely used in drying water from air compressors. In industrial production, the dryness of compressed air is usually expressed by the dew point temperature. The dew point refers to the temperature at which water vapor begins to condense through cooling and changes from vapor to liquid. The dew point of normal air compressor adsorption and drying is generally around -40°

Molecular Sieve are so named because there are uniform pores inside the particles of molecular sieves, which can separate molecules of different sizes according to the size of the pores.
