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.

La présente invention concerne un dispositif distributeur de fluide, servant à distribuer du fluide dans une colonne, ainsi qu'un dispositif collecteur de fluide servant à collecter le fluide provenant d'une colonne. Elle concerne également des procédés d'utilisation de ces dispositifs. Le dispositif distributeur et/ou le dispositif collecteur présentés peuvent être utilisés dans des réacteurs ou colonnes à lit fixe ou fluidisé, telles que des colonnes de séparation chromatographique, des colonnes échangeuses d'ions, des colonnes d'adsorption. Un tel dispositif distributeur de fluide comprend a) un premier système de transport de fluide et b) une plaque de distribution, laquelle comprend i) des premiers moyens de transfert de fluide servant à diviser l'écoulement de fluide provenant des points de distribution en plusieurs écoulements de fluide partiels et à distribuer ces derniers dans la colonne et ii) des premiers moyens servant à réguler les écoulements de fluide partiels par une pression différentielle dans les premiers moyens de transfert de fluide.
