Kwinana Pigment Plant
Our pigment plant at Kwinana is able to transform dull black synthetic rutile into more than 150,000 metric tons of pure white titanium dioxide pigment a year. The Kwinana plant uses Tronox’s proprietary chloride process technology to produce pigment used by manufacturers of paint, coatings and plastics.
Synthetic rutile is reacted with petroleum coke and chlorine in fluidised bed reactors, or chlorinators, producing titanium tetrachloride, which is purified by condensation and distillation. The remaining gases from this process are systematically treated by incineration and scrubbing.
The next stage uses a special process for reacting titanium tetrachloride with superheated oxygen and support fuel to produce a raw titanium dioxide pigment. The pigment goes through a finishing process that involves milling, classification, surface treatment, filtering, drying and micronising prior to packaging for distribution to domestic and international markets. Titanium dioxide pigment is used to whiten and brighten a wide range of consumer products – from paint and plastics to paper, cosmetics and more.
