A method and system for distilling alcohol in an alcohol production process utilizes mechanical vapor recompression (MVR), by way of an MVR device, such as to improve vacuum distillation column capacity. The MVR device is used as a way to increase vapor pressure / density and reduce vapor volume providing for increased volumetric flowrate and thereby increasing the capacity of a distillation system. In particular, the MVR takes a low value waste heat from stillage evaporators and compresses it to a higher temperature / pressure to create useful energy. By raising the pressure in the beer column with an MVR device, the vapor density increases, vapor volume decreases, and vapor velocity increases so that more vapor can be fed to and through the beer column. That is, additional mass flow can be added to the stillage evaporators and beer column to return the overall vapor velocity at the beer column to the original velocity constraint point. As such, the throughput of the beer column can be increased until it reaches its original velocity design constraint.
