In 1993 Maguin-Interis conceived and patented the first French alcohol Dehydration unit using molecular sieves or zeolites.

By the in-depth study of mass transfer in solid media and a unique conception of process automation, Maguin-Interis ensures a process having very high reliability. Therefore, units can work consistently without renewal or addition of zeolites.

Intended for Bioethanol production, the dehydration process with molecular sieves also applies to dehydrated rectified alcohol production, producing an ENA alcohol quality with very low moisture content.

Maguin-Interis also owns a Dehydration Process using azeotropic distillation.

In constant search for innovative Processes, Maguin-Interis has developed in partnership a scheme for Dehydration by the Membrane Process.
