IMPROVEMENTS IN A METHOD OF DISTILLATION AND/OR A DISTILLATION COLUMN

摘要

The invention comprises a method of reactive-distillation which includes the step of distillation of the surplus light components and separation of the heavy phase components in the same vessel. This may be achieved by utilising a reactive-distillation column having a plurality of trays. A weir is provided on at least most trays and at least most weirs have sufficient height to enable a residence time of material on the tray at least double the residence time of a conventional tray in normal distillation.
