Process for production of chlorine dioxide

摘要

The invention relates to a process for continuously producing chlorine dioxide comprising the steps of: feeding to a reactor an acid, a reducing agent and alkali metal chlorate; reacting the alkali metal chlorate with the acid and the reducing agent to form a product stream containing chlorine dioxide and the alkali metal salt of the acid; and, bringing said product stream from the reactor to an absorption tower, where it is contacted with a flow of water to form an aqueous solution containing chlorine dioxide. The invention also relates to an apparatus to produce chlorine dioxide. The invention further relates to a novel aqueous solution comprising of chlorine dioxide.
