The meaning of Liq Frac 60F in ASPEN
Thread Content
I would like to ask fellow netizens: What does Liq Frac 60F mean in ASPEN? Why are there these data for both the gas and liquid phases? Where does the calculation method come from? What is its function?
Represents the fraction of each component in the logistics
Liq Frac60F refers to the liquid phase fraction at a temperature of 60F; 60F is approximately 15℃
Since it is a liquid-phase fraction, why is this value also present when looking at the data on the overall gas-phase composition?
The result shows LiqvolFrac60F, which should refer to the volume fraction
Volume fraction, is that the correct term for identification?
I really didn’t notice that! I learned it!
I’m here to learn* as well. The original poster is really thorough; to be honest, I hadn’t seen that before – I only paid attention to the results I wanted
It is the volume fraction; I obtain this by dividing the volume of each component by the total volume flow rate, and the results are consistent with those from Liq Frac 60F. 60F is equivalent to 15.5°C, and this can be used to calculate the octane rating.
It appears only when the option ‘std.’ is selected under the report option ‘stream’; it should be the volume fraction
