If I were you, first thing I would do was to look into Perry's Chemical Engineer's Handbook, third edition dated 1950, and the current (seventh) edition.
Where to find the Perry's manual? In the library of any Chemical Engineering or Chemistry College. Here at Mackenzie University we have even the second edition. Some time ago they wanted to scrap it away because "it was too old and obsolete". Fortunately, I convinced them that to throw away an old edition of Perry is the same thing than throwing away an old edition of the Sacred Bible.
If my advice doesn't work, get in touch with Alcoa or Alcan. They may help you.
