摘要： A device and process for the separate removal of oppositely charged ions from electrolyte solutions and recombining them to form new chemical compositions. The invention provides the ability to create multiple ion flow channels and then form new chemical compositions therefrom. The process is accomplished by selectively combining oppositely charged ions of choice from different electrolyte solutions via the capacitive behavior of high electrical capacitance electrodes confined in insulated containers. Industrial plants employing the inventive process can have the flexibility to produce needed industrial chemical compounds such as Soda Ash, Caustic Soda, hydrochloric acid and chlorine gas, based on market demand, and can be located near points of consumption to significantly reduce transportation costs.

摘要： The present invention provides a process for generating acid-free lithium salt solutions for lithium and lithium ion batteries and for preparing high purity lithium salts. The invention comprises removing acid species from lithium salt solutions such as lithium hexafluorophosphate solutions using weak base resins. The process does not require the addition of a base such as ammonia which when added to the electrolytic solution generally must be removed from the final product. Once the lithium salt has been treated by the weak base resin, the substantially acid-free lithium salt solution may be recovered from the weak base resin to provide a solution which may be used as an electrolytic solution or which may be used to prepare high purity lithium salts. The highly pure salts and solutions have a hydrogen fluoride concentration of less than 10 ppm

摘要： A method and apparatus for cooling aqueous alkali metal hydroxide liquors such as, for example, caustic soda liquors, involving the vacuum cooling of a body of such liquor in an evaporating chamber having a overhead vapor outlet which communicates with a direct-contact barometric condenser supplied with a stream of cooled alkali metal hydroxide liquor. The cooled alkali metal hydroxide liquor has a vapor pressure below the absolute pressure of water vapor evolved from the body of liquor in the evaporating chamber and condenses the water vapor upon contact therewith. A stream of cooled concentrated alkali metal hydroxide liquor withdrawn from the evaporating chamber is, in accordance with a preferred embodiment of the present invention, further cooled and solids contained therein, such as, for example, sodium chloride crystals, are then removed in a suitable liquid-solids separation device. At least a portion of the substantially solids-free liquor from the liquid-solids separation device is then transmitted to the direct-contact barometric condenser for use as the condensing medium.
