A liquid mixture contains 60.0 wt% ethanol (E), 5.0 wt% of a
dissolved solute (S), and the
balance water (W). 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. (Hint: In order to
solve this problem,...
