Scale growth is a major operating issue and eventually requires equipment shut down and descaling, so all thickeners are designed to be bypassed during the descaling operation. Histo

Hydrate Precipitation, Classification and Filtration,performed in a conventional thickener. 3-stage classification flowsheets are discussed versus 2- and 1-stage and the influence on final strength of alumina is discussed as a consequence of the number of classification stages. Disc filters with large diameter discs are the standard equipment for coar

Health, Safety and Emissions to the Environment from Alumina Refineries,introduces some of the process safety issues that have occurred in the past. From there, an introduction to Functional Safety is made representing a systematic approach to deal with this subject in today’s alumina refinery design and capacity expansions. Safety aspects of operating high pressure and
