China Sphere Zeolite Molecular Sieve 3A Desiccant For Natural Gas Molecular Sieves Water Absorption Ethanol Drying Supplier

Molecular Sieve 3A is one kind of alkali metal alumino-silicate. Sometimes, it is also called 3A zeolite molecular sieve. The aperture of this molecular sieve is 3A. Therefore, It does not adsorb the objects whose molecular diameters are larger than 3Å. 3A molecular sieve's formula is 2/3K2O•1/3Na2O•Al2O3• 2 SiO2 • 9/2 H2O. 3A molecular sieve desiccant is the necessary desiccant in petroleum, chemical industry.

PRODUCTS DESCRIPTION

Product Descritpion:

 

3A EDG Molecular Sieve Desiccant is specification designed for dehydrating fuel grade ethanol,as traditional distillation of ethanol is only possible up to the azeotropic point at 95.6% volume. The preferred technology for the dehydration of ethanol to get anhydrous and fuel grade ethanol is pressure swing adsorption using 3A EDG molecular sieves. 3A EDG molecular sieve selectively adsorbs the water from the solution to produce anhydrous ethanol with less than 1% volume. This is the dehydrating process of choice for fuel ethanol product. Molecular sieve 3A EDG for ethanol dehydration not only have good water adsorption capacity, but also should adsorb methanol and ethanol as little as possible. 3A EDG uses special process to achieve this purporse. It has outstanding water adsorption capacity, little ethanol co-adsorption, high mechanical strength, low attrition. At the same time, the by-product can be greatly supressed.

Stroage:

Keep 3A EDG Molecular Sieve in an air tight container until ready for use to avoid unintended moisture adsorption.

 

Regeneration&Activation:

3A molecular sieve can be regenerated or activated either thermal regeneration method(Thermal Swing Adsorption, TSA); To remove moisture from a 3A molecular sieve, a temperature of 200-230℃ (390-570°F)is required. Molecular sieve 3A can also be regnerated or activated by lowering the pressure in the case of pressure swing processes (PSA). A properly regenerated or activated molecular sieve can give moisture dew points below -100℃. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
