Chlorine alkaline process

Process Monitoring with LiquiSonic® - Advantages at a glance

Brine treatment

When preparing the input materials for electrolysis, LiquiSonic® reliably monitors the quality or saturation of NaCl before and after preparation. In this way, additional conclusions can be drawn about the efficiency of this process step.
 


Maximum Sodium Chloride saturation saves energy costs

  • Proof the brine purity
  • Extends membrane‘s lifespan
  • Reliable incoming goods control
  • Saves energy costs by ensuring maximum NaCl saturation

Separation of NaOH and NaCl

After electrolysis, the catholyte enters the evaporator, which separates NaOH and NaCl. In addition to monitoring the quality of the separated sodium hydroxide, the NaOH/NaCl mixture can also be monitored in real time. The controller reliably indicates both concentrations simultaneously.


Highly accurate monitoring of inputs and outputs for an optimized separation process 

  • Monitoring of the caustic soda/sodium chloride mixture
  • Accuracy up to ±0.1 wt%
  • Ensure NaOH product quality

Chlorine gas drying

As a product of the electrolysis, the chlorine gas is sent for drying. By adding sulphuric acid, water is removed from the gas and thus prepared for further processing. The LiquiSonic® system monitors the quality (concentration/density) of the supplied sulphuric acid (H2SO4).


Perfect sulfuric acid concentration with no corrosion

  • Accuracy: up to 0.03 wt%
  • Automated redosing possible
