Dehydration of ethanol in azeotropic conditions (93-96 % v/v) using the Pressure Swing Adsorption (PSA) process with molecular sieves columns offers significant economic and environmental advantages.
Libra 3A Molecular sieve used to dehydrate ethanol should have the following characteristics:
• Mechanical integrity to withstand demands of pressure swings with minimal breakage or dust generation
• Adsorption effciency and selectivity to allow for rapid removal of water with minimal ethanol co-adsorption.
