Alcohol recovery in falling film evaporators

摘要

Falling film evaporators can be used to recover alcohol and other volatile compounds from waste products, and as part of the primary production process. A simple model has been developed to predict the performance of the equipment. Measurements made on commercial installations have confirmed the validity of the model over a range of operating conditions. Significant advantages arise from integrating the evaporation process into the operation of the brewery or distillery.
