DIVISION WALL COLUMN CHARACTERIZED BY THAT PRESSURE IN DICHOTOMOUS SPACES IS SUBSTANTIALLY EQUIVALENT

摘要

PURPOSE: A distillation column which includes spaces divided by dividing walls is provided to uniformly maintain pressures in the spaces by including a collector tray for regulating the drop of the pressures. CONSTITUTION: A main column includes dividing walls(51). A collector tray(C) for regulating the drop of pressures between a pre-divisional region and a main-divisional region is installed to the dividing walls in order to uniformly maintain the pressures. The pre-divisional region and the main-divisional region are divided by the dividing walls. A nozzle with a size between 10 and 30 mm is installed to the collector tray.
