Ethanol Dehydration

mSORB EDG molecular sieve is specifically designed for fuel grade ethanol dehydration. Ethanol can only be dried to the azeotropic point of 95.6% purity by traditional distillation. Our ethanol molecular sieve selectively adsorbs the water from the solution to produce anhydrous ethanol with less than 1% water. This is the drying method of choice for fuel ethanol producers.

STORAGE

Store ethanol molecular sieve in a dry location to prevent premature water adsorption. Reseal packages after opening to prevent contamination and unintended water adsorption. We recommend that you rotate stock so oldest material is used first.
