Abstract: For an n-component mixture (n≧3), an array of new distillation columns is disclosed with vertical partitions that allow independent control of the vapor flowrates in each partitioned zone, while operating the columns to produce constituent product streams. Specifically, all such more operable columns with vertical partitions for ternary and quaternary feed mixtures are illustrated. For a ternary feed, through extensive computation, the minimum heat duty for each of the new columns is same as for the FTC configuration. The new columns with vertical partitions become even more attractive when the vapor split between column sections must be controlled within a narrow range. Finally, it is disclosed how a new column with vertical partition(s) drawn for an n-component mixture can be adapted to distil feed mixtures that contain more than n-components.
