Distillation of ethanol is only possible up to the azeotropic point at 95.6% volume. Nowadays the preferred technology for the dehydration of ethanol beyond this azeotropic condition is pressure swing adsorption using synthetic molecular sieves. This dehydration step is necessary for the ethanol to meet the fuel grade standard of >99% or >99.5% ethanol. Other…
