The BSM process of dehydration of Ethanol using extractive distillation, using Monoethyleneglycol, is based on the strong affinity of the water with the glycol. The volatility of water is reduced by facilitating the release of anhydrous ethanol in the vapor phase.
This process has the following advantages:
- The dehydrator used is non-volatile and non-flammable;
- Presents reduced consumption of steam, water and dehydrating;
- It is not sensitive to slight variations in the alcoholic strength of the product.
