Model development

After a long hiatus Excel VBA and I have met again. Not to mention meeting thermodynamics and balancing chemical equations! I thought I knew most things about hot metal pre-treatment, but after extensive research and coding it myself, I now know more. It has been revealing.

Another project I am working on involves a concept design of a steel plant, and this body of work has refined my views on how things should be done.

So how do you perform dephosphorisation, vanadium recovery, desulphurisation and silicon removal in the most profitable way? I think I am beginning to understand.
