Product Details

High power rectifier for electrolysis of sodium chloride aqueous solution to produce sodium hydroxide in Chlor-Alkali Industry

Transformer-Rectifier-for-sodium-hydroxide-caustic-soda


Rectifier Application


The high power rectifier is used to provide high power for electrolysis of sodium chloride aqueous solution to produce sodium hydroxide in Chlor-Alkali Industry, the rectifier output current up to 50kA, voltage up to 800V. Mostly the current is betwen 10kA to 20kA, voltgae is lower than 800V depends on the electrolyzers design and annual capacity of sodium hydroxide(caustic soda)

High Power Rectifier for Sodium Hydroxide's Important Factors


◆ High reliability, 7*24 hours 365 days continuous running in heavy-duty

◆ High stability of output DC current

◆ Reliability of the controller, use 1+1 dule channels controller

◆ Interface with plant DCS and control room monitoring unit

◆ All necessary safety protections

◆ Reliability of the water cooling loop

◆ Anti-corrosion measures because of the corrosive fumes

Even the rectifier is small part of the whole plant investment, but it plays very critical role in the whole process.
