The Demonstration plots the feasible regions for product compositions in an ideal ternary mixture of
, where the lightest component is
and the heaviest compound is
; here the relative volatilities are 12.67, 5.35, and 1.0. You can set the feed location by dragging the locator. The yellow regions correspond to product compositions for direct split (
is obtained as a distillate while
are bottom products). On the other hand, the magenta regions correspond to product compositions for indirect split (
are obtained as distillates and
is found in the bottom).
