Solvents are mediums widely needed in chemical, pharmaceutical, food, cosmetics and other industries. Solvent selection and treating are crucial to industrial production, whether organic or inorganic solvents.
Solvent Drying and Impurities Treating
However, in many industrial processes, moisture in the solvent can have a negative impact on product quality. Therefore, water removal is an essential step in industrial production.
In addition to water, some solvents contain impurities such as sulfur and oxygenates, which must be removed to satisfy process requirements. Besides, some impurities themselves are also solvents, which make it very important to remove water and impurities in certain cases.
Molecular Sieve Solutions
As an excellent adsorbent, molecular sieve is of great value in the application of solvent drying and impurities treating. An efficient, economical, and environmentally friendly solvent treatment process can be achieved, by designing a reasonable process and optimizing the performance of molecular sieve. Compared with other adsorbents, molecular sieve has the advantages of high adsorption capacity, fast adsorption speed, good wettability and excellent thermal stability.
The process of molecular sieves in solvent drying usually includes three steps: adsorption, desorption and regeneration.
- In the adsorption step, the aqueous solvent is contacted with the molecular sieve, and water molecules are selectively adsorbed in the pores of the molecular sieve.
- In the desorption step, the adsorbed water molecules are released from the molecular sieve surface by increasing the temperature or reducing the pressure.
- In the regeneration step, the molecular sieve is heated to desorb the adsorbed water molecules and restore the adsorption performance of the molecular sieve.
SNOWPEAK specialty molecular sieve for solvent drying and treating involves type 3A, 4A, 5A and 13X molecular sieves, which can be customized according to specific solution purpose.
We can offer molecular sieves for solvents that remove water only, also provide molecular sieves that remove both water and other impurities.
