Abstract
A method of in situ corrosion mitigation in a molten salt process includes preheating a sparging gas mixture comprising a sparging gas and a carrier gas. The method also includes contacting molten salt with the preheated sparging gas mixture. The method further includes transferring impurities in the molten salt to a surface of the molten salt with the preheated sparging gas mixture. Additional methods are also disclosed.
Claims20
A method of in situ corrosion mitigation in a molten salt process, the method comprising:
- preheating a sparging gas mixture comprising a sparging gas and a carrier gas;
- contacting molten salt with the preheated sparging gas mixture;
- and
- transferring impurities in the molten salt to a surface of the molten salt with the preheated sparging gas mixture.
A method of in situ corrosion mitigation in a molten salt process, the method comprising:
- contacting molten salt in a molten salt process vessel with a sparging gas mixture, the sparging gas mixture comprising one or more sparging gasses and one or more carrier gasses;
- and
- transferring impurities in the molten salt to a surface of the molten salt with the sparging gas mixture.
A method of in situ corrosion mitigation in molten salt process equipment, the method comprising:
- preheating a sparging gas mixture;
- contacting molten salt in a molten salt process vessel with the preheated sparging gas mixture comprising hydrogen and argon;
- transferring impurities in the molten salt to a surface of the molten salt with the preheated sparging gas mixture;
- removing the impurities transferred from the surface of the molten salt;
- recovering sparging off-gasses discharged from the molten salt process vessel, the sparging off-gasses comprising the preheated sparging gas mixture and one or more of gaseous impurities, liquid impurities, and solid impurities entrained therein;
- separating at least the hydrogen from the recovered sparging off-gasses;
- and
- recycling the hydrogen.
