Cytec continues to provide the alumina industry with value-adding, efficiency-enhancing technology for all stages in Bayer Process alumina production. Cytec's technological innovations for alumina processing began with programs for the solid-liquid separation processes and the introduction of synthetic polyacrylate flocculants to replace starch.
Subsequent development of copolymers for the CCD circuit provided significant improvements in refinery economics and red mud disposal. Cytec pioneered the release of hydroxamic acid flocculants, a quantum leap in flocculant technology for the clarification circuit, providing improved economics, liquor filtration rates and reduced settler scaling.
The development of MAX HT™ Sodalite
Scale Inhibitor, a revolutionary product that eliminates sodalite
scale from heat exchangers throughout the Bayer Process, is
another testament to Cytec’s commitment to provide technologically
advanced chemistry that brings real value and contributes
to the sustainability of the alumina industry.
All of Cytec's initiatives in alumina are supported by a global
team of field engineers - and a vertically integrated supply
chain - to support today's programs and technologies with an
eye to future industry needs.
