INTERIS is a pioneer of the dehydration technology based on molecular sieves. Many patents, which are real standards in the fuel bioethanol / dehydrated ethanol production. Our reputation is based on the reliability of our units, especially the lifetime of the zeolites lasting more than 10 years.

Design of molecular sleves dehydration systems depend on the integration level of the dehydration unit in the distillery, but always with higher perfomances and lower vapor consumptions.

• Capacities from 10 000 l/d to 850 000 l/d
• 2 or 4 absorbers according to capacities.
• Column for desorption effluent concentration as an option.
• Concentration columns of purges under pressure or
• Possible integrated scheme with methanol column.
• Possible adjustment of the alcohol content up to 99,99% (100ppm).
