METHOD OF THERMAL REGULATION OF ELECTROLYZERS FOR PRODUCTION OF MAGNESIUM AND CHLORINE Russian patent published in 2018 - IPC C25C3/04 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for thermal regulation of electrolyzers for production of magnesium and chlorine. Method includes removing heat from the top of the anodes by supplying coolant to the caissons, while a propylene glycol solution is used as the refrigerant to fill the cooling system. Coolant is circulated in the cooling system by means of pumps. Heated refrigerant is withdrawn from the cooling system. Coolant is cooled in the heat exchanger. After cooling of the coolant in the heat exchanger, the electrical conductivity of the circulating solution of propylene glycol is measured, stabilize and maintain its value, by passing a circulating solution of propylene glycol through an ion exchange filter. Control and regulate the temperature, pressure and flow of the coolant before and after cooling. Then return it to the system.

EFFECT: provides increase in the service life of metal caissons and communications of cells, reducing the cost of equipment and materials for the cooling system and reducing energy losses.
