Question: 2 A liquid mixture contains 60.0 wt% ethanol (E), 5.0 wt% of a dissolved solute (S), and the balance water. A stream of this mixture is fed to a continuous distillation column operating at steady state. Product streams emerge at the top and bottom of the column. The column design calls for the product streams to have equal mass flow rates and for the top stream to contain 90.0 wt% ethanol and no S. Page 1 of 2 University of Wah, Department of Chemical Engineering a) Label the flow chart completely as per standard procedure for solving material balance b) Perform the complete degree of freedom analysis c) Select the most suitable basis
