In a pilot experiment, 100 lb-mol of a 33.0 lb-mol % ethanol, 67.0 lb-mol % water solution is fed into a distillation column and separated into two streams. The process flow diagram is shown in the image, where Xethanol, 1 = 0.330 lb-mol ethanol/1b-mol, Xwater, 1 = 0.670 1b-mol water/1b-mol, n,= 17.0 1b-mol, Xethanol,2 = 0.810 lb-mol ethanol/1b-mol, Xwater2 = 0.190 lb-mol water/1b-mol, Q1 = 19.2 lb-mol ethanol, and a2 = 63.8 1b-mol water.
