1. A system comprising:
a metallurgical furnace;
an off-gas port of the metallurgical furnace for an off-gas including a volume of carbon monoxide;
a carbon monoxide electrolyzer having an anode area and a cathode area;
an acid scrubber coupled between the off-gas port and the carbon monoxide electrolyzer and configured to separate the volume of carbon monoxide from the off-gas and provide the volume of carbon monoxide, after it has been separated, to the carbon monoxide electrolyzer; and
at least one fluid connection;
wherein the at least one fluid connection provides a fluid path for the volume of carbon monoxide from the off-gas port through the acid scrubber and to the cathode area.
