METHOD OF OPTIMIZING THE OPERATION OF A DISTILLATION COLUMN PROVIDED WITH A SIDE HEATING DEVICE |
摘要 |
In a method of optimizing the operation of a distillation column with a side heating device for reconditioning of extract which is received during the extraction of hydrocarbon-containing initial products with N-substituted morpholines whose substituents have not more than seven C-atoms as selective solvents a liquid is withdrawn to a side heating device through a chimney plate arranged above a feed plate, so that between 5 and 30 volume percent of the liquid supplied to the chimney plate is not withdrawn to the side heating device but instead supplied directly to a plate located underneath the chimney plate. A vapor-liquid mixture which has escaped through a top from the side heating device is returned back to the distillation column. The returned vapor-liquid mixture is fed either to the feed plate or to the plate located underneath the chimney plate. An arrangement for performing the inventive method is also provided.
