| titleOfInvention | Method for concentrating hydrogen halides aqueous solution |
| abstract | Method the present invention relates to be used to concentrate the aqueous starting soln of hydrogen halides, particularly hydrochloric acid, methods described comprises the following steps：In distilling apparatus (12), in the presence of extractant, extractive distillation is carried out to the aqueous starting soln of the hydrogen halides, hydrogen halides steam and/or hydrogen halide (38) are removed from the epimere of the distilling apparatus, the solution (24) containing extractant is removed from the hypomere of the distilling apparatus, the solution containing extractant that the hypomere from distilling apparatus is removed is concentrated in vaporising device (14), and the solution containing extractant concentrated in vaporising device is returned into the distilling apparatus (22), the solution containing extractant that the wherein described hypomere from distilling apparatus is removed, at a pressure exceeding the atmospheric pressure, concentrated by evaporation in the vaporising device. |
