摘要： In this disclosure, a process of recycling acid, base and the salt reagents required in the Li recovery process is introduced. A membrane electrolysis cell which incorporates an oxygen depolarized cathode is implemented to generate the required chemicals onsite. The system can utilize a portion of the salar brine or other lithium-containing brine or solid waste to generate hydrochloric or sulfuric acid, sodium hydroxide and carbonate salts. Simultaneous generation of acid and base allows for taking advantage of both chemicals during the conventional Li recovery from brines and mineral rocks. The desalinated water can also be used for the washing steps on the recovery process or returned into the evaporation ponds. The method also can be used for the direct conversion of lithium salts to the high value LiOH product. The method does not produce any solid effluent which makes it easy-to-adopt for use in existing industrial Li recovery plants.

摘要： The present invention describes ways of increasing the production efficiency of a saline water electrolysis cell and of consuming CO2 gas and sequestering it from the atmosphere. This is achieved by the introduction of CO2 gas into the catholyte of the electrolysis, where reaction of the CO2 with the hydroxide ions present in the catholyte reduces the pH of the catholyte, thereby increasing production efficiency of the electrolysis cell. The preceding reaction forms bicarbonate and/or carbonate, thus sequestering the reactant CO2 gas from the atmosphere. The CO2 gas may be introduced either directly into the cathode area of the electrolysis cell, or into the electrolyte prior to its introduction into the electrolysis cell. Corresponding apparatus is also provided.

The present invention provides a method for manufacturing lithium hydroxide, comprising: a step of dissolving lithium phosphate in an acid; a step of preparing a monovalent ion selective-type electrodialysis device disposed in the order of a cathode cell containing a cathode separator, a monovalent anion selective-type dialysis membrane for selectively permeating a monovalent anion, a monovalent cation selective-type dialysis membrane for selectively permeating a monovalent cation, and an anode cell containing an anode separator, injecting the lithium phosphate dissolved in the acid between the anode separator of the anode cell and the monovalent cation selective-type dialysis membrane, and between the cathode separator of the cathode cell and the monovalent anion selective-type dialysis membrane, respectively, and injecting water between the monovalent cation selective-type dialysis membrane and the monovalent anion selective-type dialysis membrane; a step of obtaining an aqueous lithium chloride solution, and at the same time, obtaining a phosphoric acid aqueous solution formed as a byproduct, by applying an electric current to the monovalent ion selective-type electrodialysis device; and a step of converting the obtained aqueous lithium chloride solution into an aqueous lithium hydroxide solution.

摘要： A waste water treatment system including an electrolysis treatment system and three membrane concentration systems. The electrolysis treatment system includes a first chamber that receives waste water and produces treated waste water, a second chamber that receives first recycled water and produces dilute acid discharge, and a third chamber that receives second recycled water and produces dilute caustic discharge. An anion exchange membrane separates the first chamber from the second chamber. A cation exchange membrane separates the first chamber from the third chamber. The membrane concentration system receives the treated waste water and produces a concentrated aqueous sodium sulfate product and a pure water product. A first thermal concentration system receives the dilute acid discharge and produces first recycled water and a concentrated acid product. The second thermal concentration system receives the dilute caustic discharge and produces second recycled water and a concentrated aqueous sodium sulfate product.

摘要： Method and apparatus for a low maintenance, high reliability on-site electrolytic generator incorporating automatic cell monitoring for contaminant film buildup, as well as automatically removing or cleaning the contaminant film. This method and apparatus preferably does not require human intervention to clean. For high current density cells, cleaning is preferably performed by reversing the polarity of the electrodes and applying a lower current density to the electrodes, preferably by adjusting the salinity or brine concentration of the electrolyte while keeping the voltage constant. Electrolyte flow preferably comprises water and brine flows which are preferably separately monitored and automatically adjusted. For bipolar cells, flow between modules arranged in parallel is preferably approximately equally distributed between modules and between intermediate electrodes within each module.
