METHOD FOR REGULATING WATER CONCENTRATION IN A PROCESS STREAM

摘要

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 o f free water in said process stream based on said estimating step.
