Molecular Sieve Desiccant Dehydrator
Molecular sieves are synthetically produced zeolites, a crystalline form of alkali metal (calcium, sodium, potassium) aluminosilicates, very similar to natural clays. They are highly porous, with a very narrow range of pore sizes and very high surface area per package volume. Manufactured by ion-exchange, molecular sieves possess highly localized polar charges on their surfaces that act as extremely effective adsorption sites for polar compounds such as water and hydrogen sulfide. Unlike other desiccants, molecular sieves exhibit a fairly constant rate of adsorption and equilibrium water capacity over a wide range of relative humidities. Molecular sieves are alkaline, so special acid resistant sieves are available for very sour gases.
