Abstract
A divided wall column includes: a column shell; a divided wall provided vertically inside the column shell, defining a divided wall section between an upper edge and a lower edge of the divided wall; and a liquid distributor provided within the divided wall section. The liquid distributor is fixed only to the column shell but not to the divided wall. By using the divided wall column, a defect involved in conventional divided wall columns, i.e. a maldistribution of fluid over mass transfer elements caused by a manufacturing defect of the divided wall resulted from its manufacturing process and/or a deformation thereof under operation conditions, can be minimized or even avoided.
