New Zealand – Kawerau

Thermochem lead the investigation into the severe scaling and corrosion problems related to pH-modification at the Kawerau and Nga Awa Purua (NAP) plants after start-up. Thermochem provided detailed retro‐fit designs to correct the problems. The retrofits have been installed and both plants are no longer experiencing corrosion and silica scaling problems, 2010 – 2011.
