Molecular Sieve 3D Structure
Molecular sieves can be defined as 3D structure of crystalline metal aluminosilicates which mostly perform on size exclusion principle. Molecular sieves are used as adsorbent for gases and liquids and often function as desiccant. Generally they are of many types 3A, 4A, 5A, 10X, 13X and used accordingly in different industries depending on adsorption efficiency and adsorbent requirements. Moleular sieves are available in different forms- beads, pellets and powder. Though pellets have bigger surface area but beads are readily used due to less breakage and less dust. Because of the high efficiency of molecular sieves, they are widely used in petroleum and chemical industry to remove moisture. It is also used in API and pharma companies for packaging because of its excellent drying property.
Molecular sieve desiccants – The ultimate moisture absorber
Water and moisture can play a very inconvenient role in various industrial areas. In order to purify some industrial products like different gases and liquids, removing the water or moisture becomes very important. In order to successfully complete this process, molecular sieves desiccants are used. In fact, the application of these molecular sieves has flourished massively over the last few years. These crystal compositions make it easier to absorb the moisture and other impurities and possess the pure gas or liquid. This process is much more convenient and easier compared to other procedures. The application of these sieve desiccants is seen in the industries like pharmaceutical, petrochemical, food, gas, transportation etc.
Mostly four types of molecular sieve desiccants are used in the industrial areas which are 3A, 4A, 5A and 13X sieves. These sieves are available in the form of pellets, powder and beads. Each of these molecular sieves has their different usage and importance in the industrial area. Molecular sieve is mainly used for water removal. However, the usefulness of these sieves depends on the diameter size and polarity of the sieves. These functions include natural gas drying, glass dehydration, solvent drying, oxygen purification, mercaptan remove etc.
