Process for filter aid production in alumina refineries

An improved process for the production of tricalcium aluminate (TCA) filter aid for use in an alumina refinery is described. Quicklime is slaked in a slaker tin using a suitable slaking solution to form a slaked lime slurry (10). A suitable surface-active agent is added to the slaking solution prior to slaking of the lime. Alternatively, the surface-active agents can be added to the slaked ...

Alumina Refinery: Overpressure Protection of a Filter

Most alumina refineries have multiple filters that need to be monitored for production efficiency and damage. On each of the 20 filters, safety rated pressure transmitters are used in conjunction with the STA – Safety Trip Alarm. The STA acts as the safety logic solver, used to close the final control element - a spring loaded failsafe valve.
