Molecular sieve acts as an effective absorbent for gases and liquids. Molecular sieve with a unique structure helps several systems to remove unwanted gas or liquid impurities to great extent. It can also split the gases or liquids in the form of molecular size. Molecular sieve plays a great role in the distillation of ethanol above the azeotropic point at 95.6% volume. Now, ethanol dehydration process can be carried out with the advanced technology beyond this azeotropic point with the help of synthetic molecular sieves effectively.
Molecular sieve for Ethanol Dehydration Process requires high level of purity in the range of industrial and food applications. Type 3A molecular sieves are considered as the most effective type to dry ethanol.In the ethanol dehydration process, the hydrated ethanol vapors are passed through the molecular sieve bed. As the vaporspassthe sieve bed, in the very first step water gets adsorbed by the pores of the adsorbent structure. The process of adsorption continues until the possible water adsorption from these vapors gets completed or molecular sieve gets saturated.
