3A EDG Molecular Sieve Ethanol Grade

Revised 2015

CHEMICAL FORMULA K12 [(Al02)12(SiO2)12] · nH2O

PRODUCT DESCRIPTION
DelSORB®EDG molecular sieve is specifically designed for drying fuel grade ethanol. Ethanol can only be dried to the azeotropic point of 95.6% purity by traditional distillation. DelSORB® EDG 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.
