ABOUT THE PRESENTERS
|
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.
