Again, SimSci will be able to help you with this. ALways run Compositional and treat the unknown HC components as blackoil. In my opinion you should not mess with Condensate unless your system is running single phase liquid.

Have you tried running this as Compositional-Blackoil? Unspecified components are treated as blackoil. Plus you want to see what is flashing, and when, so you need to run as Compositional. I don't use the Condensate option, but in general, V-L phase behavior prediction is what you get with Pipephase unless you are running single phase liquid only. 'But the question is will the simulation take into account of V-L equilibrium by using gas condensate option ? As in when P&T drop, minor condensation will occur to that 1.5% naphtha and will the simulation calculate it ?'Īnswer: I think it will, but you need to call up SimSci and ask them that question. RE: Pipephase Simulation dcasto (Chemical) 16 Dec 10 15:51 Has anyone came across this ? And how do we actually know it takes into account of condensation from result ? liquid holdup ? etc So what i am trying to find out is how do we define the condensate gas ratio input ?įrom my understanding is the Sm3(in liquid volume)/ Million Sm3 (in gas volume) at the current condition which is 55C and 55bar. When i tried to change the condensate gas ratio to let's say '8', it did give expected result To more specific for pipephase user, my fluid type is 'gas condensate', as for condensate source inputĬondensate gas ratio = 0 ( as it is fully vapour at that condition)Īnd the result summary showing no condensation occur throughout the pipeline which i highly doubt it ( My question is will the simulation take into account of condensation when the content reached pipe ambient temperature (26C) ? The pipeline consists of gas condensate which is fully vapour at 55 bar, 55C (from booster pump and cooled down by an air cooler). I am currently using pipephase 9.1 to determine pressure & temperature profile and flow regime of a pipeline (120km).
