Provided is a method for regulating the concentration of water in the acid feed stream in a process for the production of HF by the reaction with a fluorine containing material, the method comprising: (a) providing an acid feed stream comprising bound water and free water; (b) estimating the concentration of bound water and free water in the acid feed stream by providing a probe in said feed stream; and (c) adjusting the concentration of free water in said process stream based on said estimating step.
L'invention concerne un procédé pour réguler la concentration d'eau dans le liquide d'alimentation d'acide, dans un processus de production de fluorure d'hydrogène (HF) par réaction avec un matériau contenant du fluor. Ce procédé consiste: (a) à obtenir un liquide d'alimentation d'acide comprenant de l'eau liée et de l'eau libre (b) à estimer la concentration d'eau liée et d'eau libre dans le liquide d'alimentation d'acide en introduisant une sonde dans ledit liquide d'alimentation (c) à ajuster la concentration d'eau libre dans ledit liquide de traitement en fonction de ladite étape d'estimation.
