Aug 06, 2020 A molecular sieve consists of a sodium alumino silicate (IIRC) crystaline matrix where the spaces between the crystals are a certain uniform size. In the case of 3A, the spaces are 3 angstroms. Due to osmotic pressure water (and whatever else is smaller than 3 angstroms) is essentially forced into the sieve.

For the distillation of ethanol for gasoline addition, the most common means of breaking the azeotrope is the use of molecular sieves. Ethanol is distilled to 96%, then run over a molecular sieve which absorbs water from the mixture. The concentration is now above 96% and can be further distilled. The sieve is heated to remove the water and reused.

Some molecular sieves are used in chromatography, a separation technique that sorts molecules based on their size. Other molecular sieves are used as desiccants (some examples include activated charcoal and silica gel). For the purposes of distillation, a molecular sieve can be used to create anhydrous ethanol.

Water and ethanol form an azeotrope that limits how much water can be extracted by conventional distillation. The Vogelbusch molecular sieve system allows the dehydration of ethanol past 95 % purity. It removes water from the ethanol/water vapor mixture that exits the rectification column to gain a dehydrated product.
