Feasible Regions for Product Compositions in Ternary Mixtures

The Demonstration plots the feasible regions for product compositions in an ideal ternary mixture of

A

,

B

, and

C

, where the lightest component is

A

and the heaviest compound is

C

; 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 (

A/BC

split; i.e.,

A

is obtained as a distillate while

B

and

C

are bottom products). On the other hand, the magenta regions correspond to product compositions for indirect split (

AB/C

split; i.e.,

A

and

B

are obtained as distillates and

C

is found in the bottom).
