Abstract
A method of regenerating a platinum bath by flow reaction, the method comprising the successive steps of: drawing off fluid from the platinum bath by means of a draw-off flow; complexing platinum by mixing together the draw-off flow and a regeneration solution flow containing platinum, mixing taking place in an intensified reactor; and feeding the platinum bath with the mixture resulting from the platinum complexing step, by means of a regenerated bath flow; all of these steps being performed as a continuous flow.

A method of regenerating a platinum bath by flow reaction, the method comprising the successive steps of:
- drawing off fluid from the platinum bath by means of a draw-off flow;
- complexing platinum by mixing together the draw-off flow and a regeneration solution flow containing platinum, mixing taking place in an intensified reactor, wherein the step of complexing in the reactor comprises the steps of:
- preheating the draw-off flow and the regeneration solution flow so that their respective temperatures are equal to a predetermined temperature higher than the temperature of the platinum bath;
- mixing the draw-off flow with the regeneration solution flow so as to form a platinum complex;
- and
- feeding the platinum bath with the mixture resulting from the platinum complexing step, by means of a regenerated bath flow;
- all of these steps being performed as a continuous flow.
