Definitions

  • the system further comprises an electrolyzer maintenance module coupled to the damage evaluation module and adapted to transmit a signal representative of a maintenance action to be performed on any one of the significantly damaged or damaged cells, the maintenance action being based on the evaluation of the significantly damaged or damaged cells.
  • the methods provided herein comprise characterizing the reference voltage range for the one or more electrochemical cells in the electrolyzer during the operation (step II in FIG. 2 ), wherein the reference voltage range is dynamic dependent on factors comprising current density and concentration of the metal ions in the anolyte of the one or more electrochemical cells.
  • the methods provided herein further comprise determining the concentration of the metal ions in the anolyte of the one or more electrochemical cells and based on the determination, characterizing the reference voltage range for the one or more electrochemical cells (step I in FIG. 2 ).
  • the steps I and II may interchange in order or may be simultaneous.
  • metal ions include, but not limited to, iron, chromium, copper, tin, silver, cobalt, uranium, lead, mercury, vanadium, bismuth, titanium, ruthenium, osmium, europium, zinc, cadmium, gold, nickel, palladium, platinum, rhodium, iridium, manganese, technetium, rhenium, molybdenum, tungsten, niobium, tantalum, zirconium, hafnium, and combination thereof.
  • the “oxidation state” as used herein, includes degree of oxidation of an atom in a substance. For example, in some embodiments, the oxidation state is the net charge on the ion.
  • the methods provided herein further comprise classifying the one or more electrochemical cells as significantly damaged, damaged, or undamaged, based on the comparison or the alarm trigger (step VI in FIG. 2 ). If the acquired voltage of the cell is within the reference voltage range, the cells is considered undamaged. If the acquired voltage of the cell is outside of the reference voltage range by a small margin (is either higher than the upper range of the reference voltage range or lower than the lower range of the reference voltage range), the cell is considered damaged and the alarm trigger is generated prompting an inspection of the cell. If the acquired voltage of the cell is significantly outside of the reference voltage range, the cell is considered significantly damaged and the alarm trigger is generated also generating interlock and shut-down procedure. The significantly damaged cell may be deactivated, removed, replaced, or accessed for maintenance depending on the condition of the cell.
  • the methods provided herein further comprise measuring or checking some physical parameters of the significantly damaged or damaged cells in order to determine the reason for the anomaly in the factors, such as concentration, temperature, pressure, etc. further affecting the voltage of the cells (step VII in FIG. 2 ).
  • the physical parameters comprises current distribution, coloration of liquid exiting the cells, pressure of gas in the cells, pressure or flow of liquid entering the cells, pressure or flow of liquid exiting the cells, or combinations thereof. There may be several other physical parameters that can be measured and evaluated, all of which are within the scope of this application.
  • the physical parameters may be measured manually, digitally, and/or automatically.
  • the methods provided herein further comprise evaluating the components of the cells if an anomaly is detected in the measurement of the physical parameter (also step VII in FIG. 2 ).
  • the evaluation includes evaluating various components of the cells including, but not limited to: membrane in the cell to locate size and position of a potential pinhole; position of blockage of the flow in the cell; position of a pinch in feed line; fouling of the membrane; construction of the cell to locate leaks or warping if any; welded points in the cell to locate poor electrical distribution; or combinations thereof.
  • the evaluation may also be conducted manually, digitally, and/or automatically.
  • pinholes The occurrence of holes or tears in the cell membrane also called pinholes can cause damage to the cell dropping the cell efficiency.
  • Some reasons for the presence of pinholes and pores in the cell membrane are the formation of voids, blisters, and delaminating of the membrane due to faults in start-ups and shut-downs and by contaminated electrolytes.
  • the presence of pinholes in the membrane can affect the cell's efficiency in different ways depending on the pinhole(s)'s size and location, as well as the age of the cell.
  • FIG. 4 illustrates a system 200 , for monitoring the condition of one or more electrochemical cells in the electrolyzer, operably connected to the one or more electrochemical cells.
  • the system 200 of FIG. 4 that conducts monitoring of the system 100 of FIG. 1 is described in detail below.
  • the system further comprises a damage evaluation module D (as shown in FIG. 4 ) coupled to the comparison module, the damage evaluation module is adapted to obtain information from one or more sensors adapted for measuring a physical parameter of each one of the cells classified as significantly damaged cells or damaged cells, wherein the physical parameter comprises current distribution, coloration of liquid exiting the cells, pressure of gas in the cells, pressure or flow of liquid entering the cells, pressure or flow of liquid exiting the cells, or combinations thereof.
  • the sensor comprises one of a differential pressure sensor and/or a liquid sensor for measuring a level or flow of liquid in a cell.
  • the sensors and the analytical techniques described above may overlap.
  • the damage evaluation module may be coupled also to the factor acquisition module and may receive data related to one or more factors to measure the physical parameters.

  • the measurement method is initiated.
  • the voltage measurement data acquisition rate is set up.
  • the voltage distribution of the cells can be established by steadily increasing the current density and taking voltage measurements continuously or at predefined steps.
