    • The present invention relates to a process for recovering acids from a spent acid solution containing metal salts, the process comprising the steps of:
      -- providing a heated reactor which is split, by built-in parts, into a first reaction zone and a separate second reaction zone immediately adjoining the first reaction zone,
      -- feeding a spent acid solution into the first reaction zone of the reactor,
      -- heating the spent acid solution in the first reaction zone at a first temperature sufficient for evaporation of the water from the acid solution and for pyrolytic decomposition into acid vapours and metal oxides, wherein a reaction takes place in the first reaction zone at the first temperature, wherein the first temperature is between 250 °C and 650°C, wherein a final reaction takes place in the second reaction zone at a second temperature, wherein the second temperature is lower than the first temperature,
      -- recovering and regenerating an acid solution from the acid vapours.
