Regarding the solubility curve of gases in liquids
Thread Content
Could you please explain in detail the steps to follow in Aspen Plus? Could you provide a brief explanation regarding the solubility of H2S in water at different pressures? Those with similar questions, please reach out!
It’s possible... flash tank + sensitivity analysis
For example, let S be the solvent and A be the solute; set 50% of each in the feed to the flash tank (this value isn’t fixed – as long as it exceeds the solubility limit it’s fine). Then input these values into the flash tank model, set its pressure and temperature, and after operation, the amount of A present in the liquid phase of the flash tank will represent the solubility of that solute in S. Finally, by performing a sensitivity analysis, you can determine the solubility under different pressures and temperatures... Of course, one prerequisite is that the thermodynamic model and its parameters used must be accurate, so that the results obtained are also accurate.
4# Immolational: No matter how the feed solution ratio is adjusted, the composition of the feed and the output from the flash tank remains the same
Is it because the pressure you set for 5# cxh25 is too high, resulting in no vapor phase at all? Of course, the composition will then be the same
For 6# wycasia, the pressure is set at 1 atm
Calculate it yourself using Excel

Give it a push; I have a similar problem too
