ABSTRACT:
Offgas recycling processes, including an argon degassing embodiment which cyclically regenerates one treatment flow path while the other treatment flow path is treating the offgas. The system is changed into a second mode to regenerate the previously treating portion of the system while the offgas is being treated by the previously regenerated treatment device. A second embodiment oxidizes a copper chloride bed to release chlorine, which is injected into the melt. The offgas contains chlorine and HCl, which react with a second bed, containing oxides of copper, forming copper chloride. Water vapor and nitrogen are exhausted to the environment. Before the beds are fully reacted, the flow of gas through the beds is reversed, oxidizing the CuCl bed and reducing the copper oxides.
