Hi all,
I am considering to use MFiX to study the roasting process of a watery sulphur-metal slurry, with the intention to better determine and predict the outcome when changing the amount of water, and thereby also the temperature and in the end also the byproducts, some of which are unwanted. The process shall transform metal sulfites to oxides, so a few different reactions taking place. I am trying to find a way to do this, if at all possible, as just the combination of water as liquid, the solid products, together with air/gases, seems challenging. I have been looking at the biomass, pyrolysis and legacy examples for inspiration, and perhaps the biomass is most similar. A few questions in that regard:
- How is the particle size of the biomass set in this case? I believe it is 500μm here.
- Will this approach represent a watery slurry sufficiently, even with much higher water/moisture content? And is this amount adjusted by setting the density in the moisture species? The molecular weight there is similar to H2O.
- “Moisture” in the biomass example seems to be zero in the initial conditions, and also zero for all the BC’s. How can this be a part of the reactions at all, when the only reaction involving moisture is as a reactant, and never on the product side?
- And finally, how does “sand” have a number for Heat of formation?
Greatful for some insights here
