Before understanding the process of ethanol drying with the help of molecular sieves it is important to understand what is a molecular sieve. It is that material which is used for absorption and has selective properties. These properties are important for the purpose of separating different mixture. It depends on the type of mixture that which size and shape of molecular sieves has to be used. Molecular sieves can be used in any form that is in pelleted, beaded or in powdered form. Molecular sieves are a result of the composition of three dimensional material that is micro porous material, macro porous material and meso porous material. A single bead of molecular sieves is made with the blend of all the three. Molecular sieves are used as absorbents for various other industrial applications. According to the requirement and size molecular sieves are of various types that is 13x, 3A, 4A and 5A. So, now with the help of these efficient absorbents it is now possible to extract moisture from oils to gasses. This is the most reliable source of moisture absorbent in oil and electronic industry.
