WebDec 18, 2024 · Figure 6 depicts the extractive distillation column profile, demonstrating the efficiency of the entrainer in overcoming the ethanol/water azeotrope. The plus symbols in the x–y diagram of the ethanol/water mixture without the entrainer show the changes in azeotropic composition at high ethanol contents. The circles indicate higher ethanol ... WebApr 7, 2024 · The minimum boiling azeotrope is represented by the intersection of the two tear-drop shapes, as indicated in Figure 5.16a. this curve demonstrates why an ethanol-water mixture cannot be distilled to produce a distillate with greater than \(95.6\%\) ethanol. Imagine distilling an ethanol/water mixture of the composition at position a in Figure ...
