METHOD FOR CLEANING CHLORINE MEMBRANE ELECTROCHEMICAL CELL
The present disclosure provides a method for cleaning a chlorine membrane electrochemical cell.
1 . A method comprising contacting a component of a chlorine membrane electrochemical cell, the component having an organic deposit that includes a chlorinated organic compound coated thereon, with a cleaning solution comprising a solvent that includes diethylene glycol n-butyl ether acetate, ethylene glycol n-butyl ether acetate, or a combination thereof for the organic deposit for an amount of time to remove the organic deposit from the component, with the proviso that the component is not a membrane.
2 . (canceled)
3 . The method of claim 1 , wherein the solvent has a boiling point in the range of 175° C. to 300° C.
4 . The method of claim 1 , wherein the solvent has a water solubility in the range of 0.5 weight % to 7 weight %.
5 . The method of claim 1 , wherein the contacting occurs at a temperature in the range of 10° C. to 50° C.
6 . The method of claim 5 , wherein the temperature is ambient temperature.
7 . The method of claim 1 , wherein the amount of time is in the range of ten minutes to one hour.
8 . The method of claim 7 , wherein the amount of time is about 15 minutes.
9 . (canceled)
10 . The method of claim 1 , wherein the cleaning solution further comprises an additional ingredient comprising a hydrocarbon, a glycol diether, a high boiling point ketone, or a combination thereof.
11 . The method of claim 1 , comprising further contacting the component with a condensate flush solution.
12 . The method of claim 11 , wherein the condensate flush solution comprises distilled water.
13 . The method of claim 1 , wherein the component is an anode compartment component.
14 . The method of claim 13 , wherein the anode compartment component is an anode, a baffle, an interior surface, an anode outlet nozzle, a gas-liquid separation chamber, a de-foaming structure, a downstream pipe, equipment associated with the anode compartment, and any combination thereof.
15 . The method of claim 1 , further comprising recycling the cleaning solution.
