HYDROGEN GAS DIFFUSION ANODE ARRANGEMENT PRODUCING HCL

摘要

The present description relates to an anode arrangement for use in an electrolysis production of metals comprising an anode having a hollow body comprising a cavity, the body having at least one gas outlet connected in flow communication with the cavity. A gas inlet is connected in fluid flow communication with the cavity of the anode, the gas inlet being connectable to a source of hydrogen gas for feeding hydrogen gas into the cavity of the anode. The anode arrangement also comprises an electrical connector and a hydrogen chloride (HCl) recuperator surrounding at least a portion of the anode for recovering HCl gas released through the at least one gas outlet at an outer surface of the anode during electrolysis.

1. An anode arrangement for use in an electrolysis production of metals comprising:
an anode having a hollow body comprising a cavity extending longitudinally from a first end portion to a second end portion of the anode, said body having at least one gas outlet connected in fluid flow communication with the cavity; a gas inlet connected in fluid flow communication with the cavity of said anode, said gas inlet being connectable to a source of hydrogen gas for feeding hydrogen gas into the cavity of said anode; an electrical connector for generating a current at the anode during electrolysis; and a hydrogen chloride (HCl) recuperator surrounding at least a portion of the anode for recovering HCl gas released through the at least one gas outlet at an outer surface of the anode during electrolysis, said HCl recuperator having an outlet connectable to a HCl redistributor.
