Happy 25th Birthday to these 24/7 Scrubbers!

 23-Apr-21 An array of 12 TORBED dry gas scrubbers, each 6m in diameter, has been in 24/7 operation at New Zealand Aluminium Smelters now for 25 years providing world leading performance. 

These dry gas scrubbers remove highly corrosive hydrogen fluoride (HF) from the exhaust gases from the smelter in order to stay within discharge limits. The chart below was fist published in New Zealand's Aluminium Smelter Sustainable Development Report in 2016.
