Abstract

The present invention relates to a fluid distributing device for distributing fluid into a column and to a fluid collecting device for collecting fluid from a column. The invention relates also to methods of using the devices of the present invention. The distributing device and/or the collecting device of the present invention can be used in fixed or fluidized bed reactors or columns, such as chromatographic separation columns, ion exchange columns, adsorption columns etc. A fluid distributing device comprises a) a first fluid conveying system; and b) a distributing plate, which comprises i) first means for fluid transfer for dividing the fluid flow coming from the delivering points into several partial fluid flows and for distributing the partial fluid flows into the column; and ii) first means for controlling of the partial fluid flows by differential pressure in the first means for fluid transfer.

A fluid distributing device for distributing fluid into a column comprising:

a first fluid conveying system (1) for delivering a fluid flow to a plurality of delivering points (2);
and
a distributing plate (3) divided into a plurality of sections (7;
8), wherein each section is served by at least one delivering point (2), wherein each section of the distributing plate comprises
a fluid transfer port (4) for receiving the fluid flow coming from the delivering point (2) and conveying fluid flow into a plurality of distributing channels (5;
5b) for distributing partial fluid flows into the column, wherein a hydraulic length from the delivering point (2) to points where the partial fluid flows into the column varies;
and
first means (6) for controlling the partial fluid flows by differential pressure, wherein the first means (6) for controlling the partial fluid flows is disposed between the transfer port (4) and the distributing channels (5, 5b).
