Abstract
A method is disclosed for capture of chlorine dissociated from a chlorine-containing compound. A molten metal bath has a molten metal phase, which includes a metal or salt, and a fluid vitreous phase including calcium oxide, aluminum oxide, and sufficient silicon dioxide to cause the vitreous phase to remain fluid during exposure to chlorine dissociated from the chlorine-containing compound. The chlorine-containing compound is directed into the molten phase to cause the chlorine to dissociate from the compound, whereby the chlorine migrates to the fluid vitreous layer and interacts with the vitreous phase including calcium oxide to form an inorganic chlorinated compound, thereby capturing the chlorine from the chlorine-containing compound.
