"Figure 5 shows a form of the apparatus for separating a liquid from another of different boiling point, such as alcohol and water. The mixture is poured into retort B, and then heated to about 90 degrees C, which is above the boiling point of alcohol but below that of water. The vaporized alcohol escapes through A to the worm D. This is a simple helical coil of pipe surrounded by cold water, and serving to condense the vapor, which runs out as a liquid at the bottom. The cooling water is constantly changed by the supplying fresh cold water at the bottom and drawing off the heated water from the top." Louis Derr, 1911
