Selection of thermodynamic equations for simulating the distillation of methanesulfonic acid in PRO/II
Thread Content
I want to use Pro/II to simulate the distillation of methanesulfonic acid, but after selecting a thermodynamic equation, the methanesulfonic acid component is no longer available in the process. I would appreciate it if anyone could advise me on which thermodynamic equation would be suitable for simulating this process
I don’t understand – what does it mean that once the thermodynamic method is chosen, the components can no longer be identified? Are you using the electrolyte method? What is the relationship between other thermodynamic methods and components? Is there no such substance in the component library? How do I look at what I have here? This substance has not been simulated, and I’m not quite sure of the specific methods either. For distillation, try using the conventional NRTL first.
Hello, here’s what happened: when I selected the components, I chose methanesulfonic acid as Component 1, as shown in Figure 1. But when I entered the flow information in the process, this component disappeared, as shown in Figure 2
Huh? I have never encountered such a situation with Haiyou. Methanesulfonic acid is a solid at room temperature; try entering the temperature and pressure first, and then the flow rate information, to see if it works.
Thank you. It seems that entering the temperature first doesn’t work either; I’ll look into it further
