How to obtain the volume percentage of a stream in HYSYS?
Thread Content
Currently, only mole percentages are available; how can volume percentages be obtained in HYSYS? I could only find the Liq volumn fraction. I ask the experts! Thank you!
If it is a gas, under the same operating conditions, the volume ratio equals the molar ratio.
For pure gases and pure liquids, the value is directly equal to the molar fraction. In the case of gas-liquid or gas-liquid-solid phases, calculations must be performed separately based on their respective molar fractions and molar densities, after which these values are added together and normalized to obtain the actual volume fraction.
Logistics has several phases, and the properties of any one of them can reflect the characteristics of that particular phase; therefore, it is possible to work with either single-phase or multi-phase systems. After opening the logistics interface, widen the window and you’ll be able to see it; no need to say more… Of course, if you need the volume percentage of the components, that information isn’t available, so you’ll have to calculate it yourself.
