Complete Transformer Rectifier Solution<\/h2>\n

FRIEM supplied and commissioned a high-current AC\/DC power conversion system for a chlor-alkali plant in Brazil, rated at 350 V DC \/ 17.5 kA. The facility produces chlorine and caustic soda through membrane electrolysis of brine under continuous industrial operation.<\/p>\n

Challenge<\/h3>\n

Chlor-alkali plants operate continuously and require stable high-current DC power as a primary process input. Electrical equipment must perform reliably in aggressive and corrosive industrial environments. The conversion system represents the critical interface between the plant power supply and the electrolysis cells.<\/p>\n

Solution<\/h3>\n

FRIEM supplied and commissioned a high-current AC\/DC rectification system rated at 350 V DC \/ 17.5 kA for a chlor-alkali application.<\/p>\n

The installation is based on thyristor technology in double-bridge configuration and delivers controlled DC power to the electrolysis cells. The system is currently in operation.<\/p>\n

Outcome<\/h3>\n

The installed system provides controlled high-current DC power to support continuous membrane electrolysis. It forms a stable electrical interface between the plant power supply and the electrochemical process.<\/p>\n
