Abstract (en)
A method for converting an electrorefinery comprises the steps of: (a) short-circuiting a first section in an electrical circuit of an electrorefining unit and meanwhile: removing all electrode sets arranged for operation at a cathode spacing d1 from the electrorefining cells in the section; installing electrode sets with a cathode spacing d2 in the cells in the section, except the first and last cells; installing in the first and last cells in the section a cell bypassing device so as to bypass the first and last cells; (b) after step (a), opening the short-circuit to allow current to circulate through the section again; (c) repeating steps (a) and (b) for each of the remaining sections in the unit; and (d) interrupting the power supply in the electrical circuit and meanwhile replacing all head-bars configured for operating at cathode spacing d1 by head-bars configured for operating at cathode spacing d2. <??>A cell bypassing device is also presented. <IMAGE>
