5.3A: Overview of Vacuum Distillation - Chemistry LibreTexts

Aug 18, 2019 · A vacuum distillation is performed by applying a vacuum source to the vacuum adapter of either a simple or fractional distillation (Figure 5.48). When the pressure is lowered inside the apparatus, solutions boil at a lower temperature. Figure 5.48: Vacuum distillation variation with a simple distillation.

Dealcoholization - an overview | ScienceDirect Topics

Until the 1990s, the process required heating and evaporation of 50 to 70% of the wine to reduce the alcohol content to 4 g/liter. With the advent of vacuum distillation, the temperature required can be reduced, thus avoiding the baked or cooked character associated with heating. Nevertheless, important volatiles are lost with the alcohol.

Simply put, vacuum distillation reduces the amount of heat required to distill a "wash" of fermented material . A mechanical vacuum significantly lowers the vapor pressure of the wash, which also decreases the boiling point. The deeper (lower) the vacuum, the easier it is to boil the water-alcohol mixture at room temperature.
