ABSTRACT:
Disclosure is a method of treating a chlorine containing first gas stream in an electrolytic cell having an aqueous hydrochloride acid catholyte liquor containing catholyte compartment, an aqueous hydrochloric acid anolyte liquor containing anolyte compartment and an ion permeable barrier therebetween. According to the disclosed method the first gas stream is fed to the catholyte compartment, and an electrical current is passed through the cell to form chloride ion in the catholyte liquor. The first gas stream, depleted in chlorine content, is recovered from the catholyte compartment, while a second gas stream, containing mainly chlorine is recovered from the anolyte compartment.
