Aspen simulation of inorganic reaction problems
Thread Content
This post was last edited by Jieling on 2017-3-9 21:23. For simulating inorganic reactions in Aspen, which reactor module should be chosen? In the current model, the feed and aeration enter from the bottom of the reactor; a solid catalyst is added to carry out catalytic oxidation. The components of the feed include O2, NaSCN, Na2S, Na2S2O3, H2O, NaOH, and NaCN. What property methods should be used, and which reactor module is appropriate? Please give me some advice!
After launching the software, try using a solid template!
Where is the solid template? I’m using Aspen 9.0 right now. I haven’t used it before. Can inorganic reactions be simulated using Aspen?

Oxygen inside participates in the reaction, making it even harder to define; it’s quite confusing. During runtime, a warning appeared indicating no binary interaction.
Chemical reactions do not require bivariate interaction parameters.
Thank you! Are there other ways to simulate chemical reactions? Whether it is suitable to use Aspen for simulation.
Any chemical simulation software can be used to simulate chemical reactions, and they are generally divided into three categories: one category is designed for capacity assessment, taking neither thermodynamic feasibility nor kinetic feasibility into account, but only focusing on the balance of stoichiometric coefficients and the conversion rates of specified key components； A type related to chemical equilibrium, representing the degree of equilibrium reached…… ； There is also a category related to kinetics: per unit time and per unit volume, that is, the reaction residence time and the volume required for the reaction; it is necessary to specify concentration and rate benchmarks as well as the pre-exponential factor and activation energy...
