2002 TMS Annual Meeting & Exhibition: Short Courses—Aluminum Smelter Cell Dynamics

February 17–21 · 2002 TMS ANNUAL MEETING · Seattle, Washington




Barry Welch is in his 40th year of research and development associated with Aluminum smelting technology. He has worked in the industry as well as consulting, directing research programs and publishing extensively on aspects of smelter technology.
Alton Tabereaux is Manager of Process Technology, Alcoa Primary Metals. He graduated with a Ph.D. in Chemistry from the University of Alabama in 1971. He worked in Research and Development at Reynolds Metals Company for 26 years. He has become an acclaimed world leader in cell diagnostics and operations as well as being a regular contributor to TMS Light Metals. He teaches in the TMS Industrial Aluminum Electrolysis course as well as the international course on Process Metallurgy of Aluminum held in Norway each year. He has obtained 15 US patents and published over 50 technical papers.
Fiona Stevens McFadden has worked with Comalco for 10 years becoming their expert in modelling and design of smelting cells. She has also implemented new technology features in operating potrooms as well as having an interest in advanced process control. She has been on the Aluminum Committee of TMS and served as Light Metals Division sub-editor for the Aluminum Committee for JOM.
Jeff Keniry has been associated with aluminium smelting operations and technology development for more than 20 years. His consultancy, Alumination Consulting Pty Ltd, now specializes in process development And support to the international smelting industry. Previous roles have included Technical Manager at New Zealand Aluminium Smelters Ltd and General Manager of smelting research with Comalco Aluminium Ltd. Jeff is a past Committee member of TMS.

Who Should Attend:
This 2 day course is intended for managers, supervisors, engineers and scientists employed in either research or operations associated with aluminum smelting.

Course Overview:
There is a wide range of different cell designs and technologies operating in the world. While all striving to improve their performances, subtle differences make it difficult to simply translate practices from other smelters – the difficulties are most commonly linked with operating practices and the consequential cell dynamics. This course is aimed at providing an understanding of the causes of cell dynamics, their relative importance, early detection of the trend towards poor cell performance, and options for minimization of these so that smelter performance is maximized.

Contents of the course will include an overview of electrolytes, cell conditions, and practices for different technologies. Operating causes of process variability and the importance of super heat and heat balance. Variability in aluminum fluoride concentrations and their minimization. Options for (and importance of) regular monitoring of cells; early diagnosis of poor cell conditions; cell diagnostics. The use of models and process control for minimization of process variability.
