Hello, I am doing a project which is simulating the re-refining used lubricant oil in ASPEN HYSYS. I just started the simulation, but there are some components not available and need to be added through the HYPOTHETICAL in ASPEN HYSYS. The component I am trying to add are 1. Potassium Hydroxide 2. Sodium Sulfate 3. Zinc Oxide 4. Calcium Sulfate. The data I am trying to find to insert in ASPEN HYSYS are 1. NBP (degC) 2. MW 3. Liq Density (kg/m3) 4. Tc (degC) 5. Pc (kPa) 6. Vc (m3/kgmole) or I just need their NBP and Liq Density to calculate the other properties through the UNIFAC properties. Do you know how to find these complete information about the components? and how about this method to add components? Is this the correct method? or there are easier method to add these components? Thank you.
