After theoretical calculations, laboratory experiments and evaluation of results achieved in a pilot plant a new method has been elaborated for refining synthetic ethyl alcohol and its advantages confirmed by applying it on an industrial scale. By extractive refining distillation of raw synthetic ethyl alcohol refined alcohol can be produced which, owing to its properties, not only meets in every respect the requirements of fermenting processes, but can be used as well for many other purposes, especially in processes, where the purity of product is essential. The article deals also with the optimum design of the column for extractive distillation giving maximum yield of refined ethyl alcohol, with technologic parameters of the process and with ways how the product can be utilized. All recommendations are based on the experience acquired through experiments in a pilot plant.After theoretical calculations, laboratory experiments and evaluation of results achieved in a pilot plant a new method has been elaborated for refining synthetic ethyl alcohol and its advantages confirmed by applying it on an industrial scale.
