VAPOR AND LIQUID FLOW CONTROL IN A DIVIDING WALL FRACTIONAL DISTILLATION COLUMN |
摘要 |
Dividing wall fractional distillation columns and methods of operating these columns with greater flexibility, especially in terms of the ability to adjust the composition of the heartcut, intermediate or sidecut product fraction, are described. In particular, this composition may be advantageously "biased" toward higher or lower molecular weight components, depending on operating needs. Changes in feedstock composition may also be managed more effectively. These benefits are obtained by varying the flow rate of vapor and liquid to each side of the dividing wall. The vapor flowrate rising from an undivided portion of the column interior below the dividing wall is varied to the feed and/or product sections on opposite sides of the dividing wall. Also, the liquid flowrate falling from an undivided portion of the column interior above the dividing wall is varied to the feed and/or product sections on opposite sides of the dividing wall. |
