Chlor-alkali process
Brine preparation
During the preparation of the feedstock for electrolysis, it monitors LiquiSonic® reliably the quality or saturation of NaCl before and after preparation. This also allows conclusions to be drawn about the efficiency of this process step.
Maximum sodium chloride saturation, saving energy costs
- Reliable incoming goods inspection
- Extended lifespan of electrolysis membranes
- Exact knowledge of the purity of the brine
-
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 optimized separation process
- Monitoring of caustic soda/sodium chloride mixture
- Accuracy up to ±0.1 m%
- Ensuring NaOH product quality
- Monitoring evaporator efficiency
Drying of chlorine gas
As a product of electrolysis, the chlorine gas is dried. By adding sulfuric acid, water is removed from the gas, preparing it for further processing. LiquiSonic®System monitors the quality (concentration/density) of the supplied sulfuric acid (H2SO4).
Perfect sulfuric acid concentration for optimal drying results
- Accuracy: up to 0.03 m%
- Automated replenishment possible
- Corrosion-resistant materials (Hastelloy C2000, PFA, etc.)
- no sampling required
Chlorine gas drying
- H2SO4Accuracy up to ±0.03 m%
- Continuous real-time monitoring of H2SO4concentration
- no sampling or lab tests
- Ensuring the desired Cl2dryness to prevent corrosion
Separation in the diaphragm process
- No more sampling required
- True 24/7 process control
- Continuous monitoring of the concentration of the NaOH/NaCl mixture
- Reduction of energy costs during evaporation
- Exact adjustment of the customer-specific product NaOH concentration
