For an assignment I was working on, I needed to reference the critical temperature and pressure for a hydrocarbon mix. For the particular stream, I used the "critical properties" utility, which displayed "true" and "pseudo" temperatures and pressures.
What do you recommend for sizing control valves, true or pseudo critical pressure? What do you think for hydrocarbons (diesel, fuel oil, HVGO...)?
The difference between both values may be significant in some cases, which affects the control sizing calculations.
If anybody is able to shed some light on this issue, i'd be greatly appreciative
Thanks,
