How can I find the vapor pressure??

Dear netizens, I used Hysys 3.0 to model the components of a certain fuel with D86 content. After adding the oil to the system, I set the temperature and pressure in the stream and specified that the state should be liquid. How can I determine the vapor pressure of this oil from the stream?

Given a vaporization rate of 0 and a temperature value, the pressure is calculated automatically; this pressure represents the saturated vapor pressure at that temperature

That’s great; it’s really enlightening. Thank you

Alternatively, Aspen can be used to determine the PL of a substance, and then Excel can be employed to perform calculations using mole ratios
