HYD03C: EthaDry

Products for Ethanol Dehydration Units

EthaDry – 3A molecular sieve
We considered the conditions that dehydration units need to be able to operate at peak performance and designed a molecular sieve with ideal physical properties and selectivity to optimize productivity.

Product Application

EthaDry is specifically manufactured for use in Ethanol Dehydration Units (EDUs) to remove water from ethanol streams. This dehydration process creates a fuel grade ethanol that can be used for direct blending and ETBE production, chemical manufacturing, pharmaceutical production, and more. This molecular sieve has a high selectivity for water over ethanol molecules, which can increase both operating efficiency and capacity.

  • used for the dehydration of ethanol
  • capable of removing water to less than one percent
  • allows ethanol to be used in biofuels, chemical manufacturing, pharmaceuticals
  • offers advantageous crush strength, adsorption capacity, and selectivity for water

Why does using Hengye Sieve for Ethanol Dehydration matter?

The Mass Transfer Zone (MTZ) is strongly effected by the properties of the molecular sieve being used. Bulk density will change the speed at which the beads become saturated and can alter both cycle time and the overall adsorption capacity of the bead. If the Mass Transfer Rate (MTR) is slow, the MTZ is increased, which causes a breakthrough to occur while much of the bed still remains useful. A faster MTR is ideal for getting the most use out of your dehydration units each cycle.
