Abstract
A method of destroying a fluorocarbon compound includes regenerating an adsorbent to remove the fluorocarbon compound and to produce a regeneration fluid having a concentration of the fluorocarbon compound and directing the regeneration fluid to an electro-oxidation system. The method also includes applying a current to the electro-oxidation system to oxidize the fluorocarbon compound within the regeneration fluid and measuring a quantity of fluorides in the regeneration fluid to determine the progress of the removal of the fluorocarbon compound from the regeneration fluid.
Claims10
A method of destroying a fluorocarbon compound, the method comprising:
- regenerating an adsorbent to remove the fluorocarbon compound and to produce a regeneration fluid having a concentration of the fluorocarbon compound;
- directing the regeneration fluid to an electro-oxidation system;
- applying a current to the electro-oxidation system to oxidize the fluorocarbon compound within the regeneration fluid;
- and
- measuring a quantity of fluorides in the regeneration fluid to determine the progress of the removal of the fluorocarbon compound from the regeneration fluid;
- wherein the current has a current density of at least 5,000 A/m2.
A method of destroying a fluorocarbon compound in a flow of water, the method composing:
- directing the flow of water into a tank containing an adsorbent;
- removing the fluorocarbon compound from the flow of water by facilitating the adsorption of the fluorocarbon compound with the adsorbent;
- periodically regenerating the adsorbent to allow for re-use of the adsorbent, the process of regeneration comprising,
- placing the adsorbent in a regeneration fluid, the fluorocarbon compound de-adsorbing from the adsorbent and collecting in the regeneration fluid;
- directing the regeneration fluid to an electro-oxidation system;
- applying a current to the electro-oxidation system to oxidize the fluorocarbon compound within the regeneration fluid;
- and
- measuring a quantity of fluorides in the regeneration fluid to determine the progress of the removal of the fluorocarbon compound from the regeneration fluid;
- wherein the current has a current density of at least 5,000 A/m2.
