EnSieve^® Molecular Sieve for Ethanol Dehydration

With over 50 years of experience, Grace Davison has become a global leader in developing, manufacturing and marketing commercial molecular sieves for a variety of drying and purification applications.

One example is the drying of ethanol, which is only possible to the azeotropic point by traditional distillation techniques. In order to obtain ethanol contents higher than 95%, water removal with molecular sieve beads in either gas or liquid phase is the method of choice.

Grace Davison's EnSieve^® MS 562ET is a 3A molecular sieve designed exclusively for ethanol dehydration. This product offers several unique benefits including:

• Superior rate of adsorption achieved by control of the meso and macropore structure of the beads allowing users to achieve ultra-dry ethanol.
• High physical strength through our choice of binder maximizing crush strength and minimizing dusting and breakage of the beads exposed to the rigors of Vacuum/Pressure Swing Adsorption
• Extremely low reactivity levels due to the binder selection which minimizes side reactions such as the formation of aldehydes and ketones, critical contaminants in pharmaceutical and other specialty applications of ethanol.
• Tight bead particle size distribution affording uniform flow distribution of vapor phase ethanol and consistent drying

Grace Davison is not only a supplier of superior adsorbents, we also provide comprehensive customer service to enable optimal value contribution by our products to our customers' processes.

Committed to a full adsorbent life-cycle concept, we provide a complete service from the conception of the unit to advice about the replacement of the adsorbent after its lifetime.
