Questions regarding phase equilibrium data
Thread Content
I am now carrying out the distillation of hydrazine hydrate and water; the bottom of the tower contains 25% hydrazine hydrate, while the top is almost pure water. After determining the gas-liquid equilibrium of hydrazine hydrate and water, I obtained the phase equilibrium data at atmospheric pressure. How can these phase equilibrium data be applied in a distillation column? 2. Also, I determined the hydrazine hydrate content using chromatography; when the concentration of hydrazine hydrate is below 15%, the chromatography method shows almost no response to the peak corresponding to hydrazine hydrate. Can I use the data from concentrations above 15% to perform regression analysis in Aspen in order to obtain values for concentrations below 15%? 3. In Aspen, there is only hydrazine, no hydrazine hydrate. Should I generate hydrazine hydrate virtually, or can I simply use mass conversion? 4. What is used within property to simulate the binary equilibrium phase diagram? Thank you!
If you have the thermodynamic data for hydrazine hydrate and water, you can import it into ASPEN and then perform distillation simulations...
Could you be more specific? Do you mean their interaction parameters and things like that? And is it about creating a virtual substance? Because Aspen doesn’t have hydrazine hydrate
You can use Aspen Properties to fit your experimental data
