Smartdiver at alumina settler was used to accurately and reliably track key measurements during startup of a newly modified settler in a USA refinery.
The continuous measurement of clarity, interface, mud, heavy mud and tank profiles are key parameters for efficient CCD and settler control.
The use of Smartdivers has proven to be critical for process optimization especially in the global metals minerals and mining industries.
For the first time in the history of the alumina industry, a single Smartdiver was used to accurately and reliably track these measurements during startup.
The trends below reflect a tank flare and the subsequent variations during the upset.
The ability to track and monitor these parameters proved indispensable in stabilizing the flaring vessel while optimizing flocculants addition.
There were no flow or density measurements, resulting in operators relying exclusively on Smartdiver to control underflow solids based on compact bed level measurements.
The ability of the Smartdiver of distinguishing mud from the significant more densely compact mud bed and tracking mud levels was critical for optimizing thickener control during this operation.
