Apparatus for treating the compounds in a corrosive liquid comprising a fixed tank in which the liquid is placed, a horizontally axed rotary support which peripherally carries at least one bucket for receiving the compound to be treated, means for introducing the compound into the bucket, means for removing the compound from the bucket, means for rotating the rotary support about its shaft and means for guiding the rotary support during its rotation about its shaft, wherein the guidance means are entirely arranged within the tank, the guidance means and the driving means being positioned above a horizontal plane passing through the axis of the rotary support.

Apparatus for processing compounds in a liquid, wherein it is constituted by a helical vibrating elevator having a tank with a vertical axis, a fixed cover, an annular helical ramp fixed to the tank wall, means for imparting a reciprocating movement about its axis and in a vertical plane to the ramp, said movement being such that the rotation speed of the ramp in one direction exceeds the rotation speed thereof in the opposite direction, at least one liquid supply pipe in the cover, at least one lateral discharge opening for the liquid in the tank, a supply chute for the compounds carried by the cover and whose axis coincides with that of the tank and a discharge chute for the compounds located at the top of the helical ramp and in an extension of the latter. The apparatus can in particular be used for the continuous dissolving of nuclear fuels in nitric acid during the reprocessing of said fuels.

The method of recovery of hydrogen chloride in gaseous form from an organic solvent loaded with hydrochloric acid in a dilute aqueous solution consists in carrying out prior to distillation a dehydration of the loaded organic solvent in a dehydration extractor in which the solvent is circulated countercurrent to an aqueous solution having a high chloride concentration.
