Abstract
Provided are novel methods and systems for separating a mixed gas containing oxygen and chlorine. According to one method in accordance with the invention, the mixed gas and a refrigerant are introduced into a separator unit. At least a portion of the chlorine is condensed from the mixed gas in the separator unit, thereby forming a condensed chlorine-rich liquid fraction and an oxygen-enriched gas fraction. The condensing duty is supplied by the refrigerant, which can be liquid oxygen. The mixed gas and refrigerant can be brought into direct or indirect contact with one another. The invention can be advantageously applied to the treatment of exhaust gases from an ore treatment plant, and can result in enriched oxygen and chlorine streams which may be recycled or used in other applications.
