Hi Friends,
Liquor preparation tanks in Alumina refinery are popularly known as Test tanks. Test tanks are the storage vessels mixed liquor used for digestion, Evaporator product liquor, Evaporator wash liquor and Fresh caustic soda. These vessels are cylindrical vessels with top cover in order to combat rain water entry to the tanks. In general, agitators are not required for such duties as solid content in liquor is negligible.
In present post, the design calculations for Test tanks have been developed and presented in simplified forms as outlined below-
The above calculations have been developed for a typical capacity, however, design of test tanks of any capacity can be done using this methodology by simply inserting the basic data and variables as applicable.
We seek your views / suggestions / remarks / comments for further improvement.

Is this applicable for designing the precipitation tanks (for growth purposes) in the precipitation circuit? What is the difference in terms of mechanism and features between the precipitation tanks for agglomeration and growth?
