The method for managing the polarity-reversal frequency of at least one pair of electrodes in an electrochemical reactor for water electrolysis includes observing a fluctuation in the hydrogen potential (pH) of the water, while carrying out a comparison of the pH measured at a given moment with a previous measurement or a predetermined initial value. An amount of treatment agent is injected into the water to adjust the pH to around a defined set point. The polarity-reversal frequency of electrodes is calculated on the basis of the temperature of the water, the pH fluctuation and amount of agent injected. The method includes estimating the total alkali strength on the basis of the injected amount and the pH fluctuation, anticipating the fluctuations in the pH relative to the preceding estimations, and readjusting complete alkalinity titration estimate and calculation of the polarity-reversal frequency.

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.

Electrooxidation at elevated pressures

Номер: US20190047881A1
Автор: Bryan J. Kumfer
Принадлежит: Siemens Energy Inc

There are provided electrooxidation systems and processes which provide an elevated pressure at which components are oxidized in an electrooxidation cell.
