Equilibrium Codes
Equilibrium Codes
(OP)
We have one Fluent programmer in our multi-billion dollar organization and it takes two weeks for him to get chemical equilibrium results let alone build a model. I use an old FORTRAN program (1976) that works well in a few seconds and gives me hundreds of species but it is not corporately approved so I have to run the equilibria at home and bring in the results. Does anyone else have similar problems with getting corporate approval for software? Why are large companies IT people so retarded when it comes to understanding software? I have been double booting in LINUX for 15 years and use fractal generators, OpenFOAM, etc. with great results but the biggest companies are terrified of LINUX and take decades to test even new MS programs like Windows. I learned in the old days of computer cards so I am no junior engineer but I have kept abreast of the technologies. (I think our VP of IT still uses computer cards.) We spend tens of millons of dollars every year on licenses that are effectively worthless.

Does this FORTRAN program use actual experimental data (database) or estimate equilibrium data using group contribution methods (UNIFAC)? When I was a puppy, I put a thermo model together for the distillation train in our synthetic ethanol unit under the watchful eye of a published, triple PhD, thermo mastermind. I did a lot of research to obtain experimental data. Some I had interpreted from German and Russian. It turned out to be a very good model, but it took me a few months. 3-4 months, if I remember right. It had about 10 components, maybe a few more than that. Difficulty is proportional to (number of components)2.
Good luck,
Latexman
