What software can be used to determine boiling points and boiling point compositions under different pressures?
Thread Content
I want to separate toluene and methanol. The solvent ratio is 1 to 1. But it is a solvent in the manufacturing process. A purity of around 95% is sufficient for separation. I want to separate it through pressure reduction. I don’t know where I can find the relevant data. Thank you.
Process simulation software, such as ASPEN PLUS.
Using ASPEN and selecting appropriate equations such as NRTL to plot TXY diagrams allows for the analysis of changes in phase diagrams and boiling points under varying pressures. However, the boiling point of this system may not be sensitive to pressure changes, and methods such as extractive distillation might be necessary to address this issue; pressure-driven distillation could work if energy consumption is not taken into account. Each specific issue should be analyzed on its own.
If no data can be found, Aspen must be used; the database can also be adjusted based on the parameters you checked
