Hello,
I am facing this problem while using Aspen Hysys. I have a stream containing about 99% mass of air at -110°C and phase fraction (vapor) of 0.9983. The liquid phase contains water and a VOC (volatile organic compound).
What is the best way to separate the two phases?
I tried a flash separator but the results don't seem right (is it possible to separate them by a simple separator?)
I tried a short cut distillation but putting the values to Light and Heavy key components doesn't seem to work either.
How should I separate it ?

Hi ,
You may consider an adsorption process , using activated carbon !
I guess it's a typo -110C .
Hope this helps

If you are using a built-in 'air' component, you may get better flash results using nitrogen-oxygen mix. If the results are still unreasonable, your thermodynamic system settings are inadequate. The short-cut distillation unit is based on the flash, so if the flash separator is wrong, all the other equilibrium separation units will also give wrong answers.
I would be surprised if you really have much water in a liquid phase at -110C. Ice crystals are more likely.
