your liquid phase vapor fraction equal to 0 (it doesn't account the vapor bubbles/droplets) and vapor stream vapor fraction is equal to 1(it doesn't consider any liquid carryover).But we can simulate the sepeartors as Real seperators which will give an option to put the mesh pad thickness and all releted information.Chemical Process and Product Design Aspen HYSYS : Steady states and Dynamic Simulator (Introduction) nothing but Hysys always give 100 % sepeartion i.e. This is an additional information,Instead to model the seperators in hysys by the hysys default method i.e. heavy and light liquid.Hysys will perform the calculations only thing is that even though you don't have any flashing so no vapor flow still connect the material stream for the O/H vapor. It is not a big deal.If you have the specifications of your feed stream.Just pick the 3 phase sepeartor.Even though you don't have 2 phase flow stream as your problem is to sepearte the 2 liquids based on their density difference i.e.
