Abstract

A fixed packing pulsed column has a combination of single plates or groups of plates of the disc-and-doughnut baffle or slotted tray type and single or multiple perforated plates, pref. with some of the perforated plates interspersed between the other type of plate. A group of perforated plates is pref. located at the upper and lower ends of the column. Vane-type coalescing plates are pref. included in the packing, imparting a helical movement to the two phases in the column. The perforated plates are pref. closely spaced, when grouped, while the spacing between disc-and-doughnut or slotted plates is greater, depending on the dia. of the column, so that the lateral flow path is of the same order as the axial flow path. The column is used for contacting two immiscible phases of different density with a view to transferring a solute from one phase to the other (extraction) or to reacting components of the two phases. The phases are pref. liqs. but one can be gaseous phase. For this type of column, plates of the disc-and-doughnut type are preferable, since they do not require wetting by the continuous phase, and so can be made from cheap materials, e.g. plastics, rather than stainless steel used when corrosive materials are involved. For larger dia. columns in partic., the spacing between the plates increases unacceptably, decreasing efficiency. The combination of two types of plates overcomes this problem, without having to use costly material exclusively.
