Abstract: One-stage process results in complete removal of Cl2, COCl2 and HCl from effluent gases produced during the mfr. of Al by reaction of alumina or bauxite with Cl2 in the presence of CO or C. The purification is carried out using a 0.1-30 wt.% FeCl2 soln. having a pH between -0.7 and +1.5 pref. 0-1.0. between room temp. and the boiling point. The spent FeCl2 soln. is pref. regenerated with iron scrap and recycled.

Abstract: Disturbances occurring in chloride-caustic cells using the amalgam method are caused by felty coatings which form on the bottom of the cells. These disturbances can be avoided by treating the mercury (after it has left the decomposer and before or after it has entered the electrolytic cell) with an aqueous solution which contains chlorine and/or ferric chloride.
