Aspen limestone gypsum process simulation assistance requested
Thread Content
I have been working on a limestone-gypsum process recently, which involves the oxidation of sulfite ions in a reactor, as well as the combination of calcium ions with sulfate ions to form gypsum. The reaction is shown in the figure below, where SALT2 represents calcium sulfate dihydrate (gypsum product), and CALCL represents calcium sulfite. The reaction results are shown in the figure below; it can be seen that no SALT2 was formed, only the oxidation products, sulfate ions and calcium ions. My assumption is that it is caused by excessive water consumption for absorption. I would like to ask the experienced members of Haichuan Forum how I can solve this problem?
May I ask how your limestone slurry is simulated?
Exactly the same situation – has the building management team resolved it yet? Can I contact them via QQ? 2548472389
