Dear All,
i am doing some Unisim simulations to check the adequacy of Choke Valve / Control valves (CV) on the Gas Well flowlines. I am using 'Critical Property' Utility for this as in the latest Unisim version R451.3.
I notice that, I am not getting True Critical properties for some of the streams (GOR adjusted) coming from some wells. It shows only Pseudo properties but as i know they are not realisitc so cant be used for choke valve / CVs sizing. Whereas if i separate the stream in a separator, i can get True criical properties for induvidual stream but agian not for all.
1. What is the reason? Can there be a stream without True Critical Properties?
2. What data to use for control valves sizing in this case?
