Abstract
A hydrogen chloride removal process includes (i) contacting in a reactor an aqueous solution, which includes one or more Fe2+-compounds, with a fluid, which includes an oxidizing agent, hydrochloric acid gas and optionally chlorine gas; and (ii) oxidizing the Fe2+-compounds to Fe3+-compounds, thereby converting the fluid to an exhaust gas, which has a reduced hydrochloric acid content.
