Abstract
An electrochlorination system comprising an electrochemical cell including a housing having an inlet, an outlet, and an anode-cathode pair disposed within the housing, a source of a chloride-containing aqueous solution having an outlet fluidly connectable to the inlet of the electrochemical cell, and a source of an oxidizing agent fluidly connectable to the source of chloride-containing aqueous solution upstream of the electrochemical cell.
Claims15
A hydrogen abatement system comprising:
- a source of an oxidizing agent fluidly connectable to a source of a chloride-containing aqueous solution;
- a plurality of sensors constructed and arranged to measure at least one operating parameter of an electrochemical cell including a housing having an inlet in fluid communication with the source of a chloride-containing aqueous solution;
- and
- a controller configured to regulate introduction of the oxidizing agent into the chloride-containing aqueous solution based on the measured value of the at least one operating parameter from the plurality of sensors to an amount sufficient to abate hydrogen gas in the electrochemical cell, the at least one operating parameter comprising at least a pH of the chloride-containing aqueous solution.
