Rectification covers all steps of raw alcohol treatment (phlegm) for the production of Rectified Alcohol (Industrial quality) or Rectified Extra Neutral Alcohol (REN - Superfine - ENA).

The expertise of Maguin-Interis is inherited from knowledge passed on generation to generation by "distillers" pioneered by the famous Emile BARBET. Therefore, the quality of alcohols obtained by Rectification units has resulted in Maguin-Interis being a reference for the major alcohol producers.

In order to continuously improve its Rectification process, Maguin-Interis set up specific simulation tools allowing the selection of extraction products to be optimized, by considering for each of them the chemical and organoleptic aspects.

This development led to a complete mastery of the installations and to impurities management in the various stages of the Process: Hydroselection (or indirect purification), Rectification, Refining and Low Grade Concentration with specific purification stage. So the extraction rates are minimized, while ensuring a high quality of the neutral alcohol produced.

The proposed schemes are with multiple effects using columns under vacuum and/or with vapour recompression, leading to the best energy performances.
