General Use 3A Molecular Sieve is Most Commonly Used for Dehydration Applications that Require all Feasible Water Content to be Removed from a Desired Product Stream. Some Saturated Mixtures, known as Constant Boiling Point Mixtures, Cannot be Dehydrated through Distillation Alone due to Naturally Occurring Zeotropes. When a Zeotrope is Reached, Molecular Sieve Technology can be Applied to Continue the Dehydration Process and Achieve A Drier Composition for these Mixture Streams. Type 3A Zeolite can Dehydrate Various Saturated Solutions, even When a Zeotrope Does Not Occur, and is Widely Applied as a Bulk Dehydrator for Increasing the Quality and Purity of Product Streams.

How it works 3A Molecular Sieve has a Pore Opening of Approximately 3 Angstroms in Diameter and is Perfectly Wide Enough to Allow the Adsorption of Water Molecules, which have a Molecular Diameter of About 2.8 Angstroms in Diameter. While Water can Fit Inside of the Molecular Sieve Crystal, Hydrocarbon Chains such as Ethanol (approx. 3.6 Angstroms) Won’t be Adsorbed by the Molecular Sieve due to their Larger Molecular Diameters, which Prevents the Hydrocarbons from Being Able to Fit Through the Pore Opening of the 3A Zeolite Crystal.
