ABSTRACT:
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.
