摘要： The present invention provides a process for selectively separating HF and like acids present along with water-unstable organic acid fluorides. In particular, the invention provides a process for separating an acid from a system in which the acid and an organic acid fluoride are present, the organic acid fluoride being represented by formula (I):

        RCOF     (I)

wherein R is a fluorine atom; a C 1-20 linear, branched or cyclic alkyl or halogenated alkyl group that may contain a heteroatom; or a C 6-20 aryl or halogenated aryl group that may contain a heteroatom; the process comprising using as a deacidifying agent an aromatic heterocyclic compound having a boiling point of at least 50°C and having one or more nitrogen atoms as heteroatom.

摘要： The invention concerns an uranium oxide production plant comprising a reactor (2) wherein uranium hexafluoride UF6 is converted into uranium oxyfluoride UO2F2 which is obtained in powder form and wherein gaseous hydrofluoric acid is produced and evacuated from the reactor (2) through a globally cylindrical filtering wall (12) with vertical axis (10') of tubular filters (10) fixed on the upper part of the shell of the reactor (2). The filters (10) separate the uranium oxyfluoride powder from the evacuated gases. The wall (12) of the filters (10) is backwashed by periodically injecting an inert gas jet inside the tubular cylindrical wall (12) of each filter (10). The inert gas is injected along the axis (10') of the cylindrical wall (12) of the filter (10), in jet form at a speed higher than 300 m/s, for a duration less than 1 second. Preferably, the backwashing inert gas is injected into the shell (12) of the filter (10) with a nozzle (28) arranged in a manifold (11) recuperating the gases evacuated at the outlet of the filters (10) and placed in the axial alignment of a venturi (30) formed by an opening passing through a flange (22) supporting and fixing the filter (10) on a plate (9) separating the gas-recuperating manifold (11) from the internal space of the reactor (2).
