This new treatment approach provides results comparable to traditional chromate programs over a wide variety of water qualities and system conditions.  This paper presents the results of this treatment approach applied at Ciba-Geigy's St. Gabriel, Louisiana Plant.  Corrosion rates at the plant have been less than 0.4 mpy on carbon steel coupons, while eliminating the fouling previously experienced due to inorganic loading.  The program takes advantage of the synergistic protection provided to carbon steel by diol technology without requiring the use of organic inhibitors.
