ABSTRACT:
A process is shown for treating flue or exhaust gases in order to remove sulfur oxides and hydrochloric acids in which calcium hydroxide having a surface area of at least 25 m.sup.2 /g and a moisture content lower than 50% is injected in the gases to be treated either alone, or in a mixture with magnesium hydroxide. The calcium hydroxide used in the process is prepared by reacting quicklime or dolomitic quicklime with water in the presence of a glycol or an amine companion additive.
