Distillation process to separate mixtures containing three or more components
The heat requirement of conventional distillation processes which separate feed mixtures containing three or more components is reduced by sending a liquid bottoms stream 20 (or gaseous overhead stream 230) containing two or more components from an earlier column to a subsequent column and returning...

| description | The heat requirement of conventional distillation processes which separate feed mixtures containing three or more components is reduced by sending a liquid bottoms stream 20 (or gaseous overhead stream 230) containing two or more components from an earlier column to a subsequent column and returning a vapor stream 227 (or liquid stream 337) between the same locations in the two columns. A portion 24 (234) of the liquid bottoms stream 20 (overhead vapor stream 230) is at least partially vaporized (condensed) prior to feeding to the second column or heat is added (removed) from the second column between the feed location of the entire liquid stream 20 (gaseous stream 230) and the bottom (top) of the second column. |
