| OBJECT: |
A hot fatty organic acid containing 18-23% powdered Cadmium Oxide. |
|
PROBLEM: |
Cadmium oxide is a dark red powder that does not disperse well in this low viscosity (100-500 cps) fatty acid when using a turbine agitator in a 5,000 gallon process vessel. The final product when cooled to room temperature looks like solid wax with particles of Cadmium Oxide ranging from 1/16" to 1/8". These particles are actually very soft agglomerations of a fine powder. Since a chemical reaction is occurring between the acid and the Cadmium Oxide, these undispersed specks do not react and give inferior final product quality. |
|
RESULT: |
The Reversible Homogenizer was able to substantially reduce the number of agglomerations. The reaction rate and yield were increased. |
|
AB MIXER: |
Model C-3-1 Reversible Homogenizing mixer, 15 HP, 3600 RPM installed in tandem with existing turbine mixer. |
