  • Method for softening lithium brine using nanofiltration
    Patent number: 11203542
    Abstract: Lithium brine is treated with a multiple pass nanofiltration (NF) membrane system. Sulfate is added to permeate from an upstream pass before it flows through a downstream pass. Optionally the sulfate may be added to the permeate by dosing it with sulfuric acid or a slat such as sodium sulfate. The softened brine may then be processed further, for example by a combination of solvent extraction, electrolysis, crystallization and drying, to produce a lithium hydroxide product that can be used to make batteries.
    Type: Grant

  • System and method for monitoring an integrated system
    Patent number: 8216517
    Abstract: A control system includes an estimator configured to determine a present state of a device and compare the present state of the device with an expected state of the device. The control system further includes a predictor operatively coupled to the estimator, and configured to predict an event for execution by the device to reach the expected state of the device. The control system also includes a supervisory control unit operatively coupled to the predictor and the device, and configured to facilitate execution of the predicted event by the device.
