Reaction column by physical or physico-chemical process in the heterogeneous phase. According to the invention, such a column operates under a pressure which is substantially equal to the height of charge in the column; its lower part (2) is conical, the lining comprises a static component (5) and layers (6, 7, 8) of inert materials with a size and density increasing from top to bottom are arranged in the cone; a free height (H1) is left available between the top of the upper layer (5) and the top of the column. Applications for the treatment of solutions in general. |
