The AGA method uses a frictional pressure drop calculation originally developed by Dukler and an elevation pressure drop calculation originally developed by Flanigan. 363-367ĪPI RP 14E has an equation (equation 38) that is derived from the general equation for isothermal flow assuming that the pressure drop is less than 10 percent of the inlet pressure. Griffith, "Multiphase Flow in Pipes," JPT, March 1984, pp. Regardless what you use, even the best correlations available for pressure drop and liquid hold up will be in error by as much as 20% for horizontal flow (and up to 50%for verticle flow). The type of flow pattern depends primarily on the gas and liquid flow rates. Morten RE: Modelling and simulation of gas/gas condensate in gas pipelineĪ gas-liquid mixture in a horizontal pipeline, like you have indicated, tends to separate with the heavier liquid settling to the bottom.
#Pipesim sim software
While i find that winsim is an excellent piece of software at the price and the basic principle of their pipemodel to be very good - they do lack behind in multiphase models somewhat.
#Pipesim sim license
While you may find it tedious some people want so much more details these days that the backside of an envelope dosnt cut it anymore.īesides - apart from bying the OLGA license you may also hire a consultant. Since it appears that its 10+ years since you did flow simulation just as with drillign related issues (that i dont know much about) tehre is a development going on in flowmodelling and flow assurance.
#Pipesim sim how to
If you DO have a HYSYS license then i think the SS OLGAS module might come out the cheapest - and if you allready know how to use HYSYS then it very easy to use. You dont knwo anything about pipelinelength, production rates, topology or.īesides while OLGA transient IS rather expensive (around us$200,000 last time i checked for a single license) then you can get a SS module that integrates with HYSYS for a MUCH lower price and it give consistent answers with the dynamic model (but then you are back to SS). How can you conclude this when you don know what he wants to analyse? It may be that he needs to size slug catchers (yes he hasnt said anything about this but it wouldnt be the first time in history that a "small subject" bloomed into something bigger). RE: Modelling and simulation of gas/gas condensate in gas pipeline MortenA (Petroleum) 10 Apr 07 02:56 Pipeflo is available from Neotec, on a per run basis if necessary from Pipesim is now owned by Brother Blue, more info at htt p://ent/servic es/softwar e/producti on/pipesim /index.aspĪnd pipephase is available at ww.simsci- /us/eng/pr oducts/pro ductlist/d efault.htm Ideally you want to be able to do the same sort of thing with your pipeline model. You might also want to try and read up on the different correlations: I know that in vertical flow (ie up an oil well rather than along a pipeline) Beggs & Brill usually overpredicts pressure loss and Fancher-Brown underpredicts pressure loss so I use these two correlations as quality control in my well modelling. Run the model with as many different phase correlations as you can, to get a performance 'envelope'. I was most familiar with Pipeflo, which I found very good, and I didn't like Pipesim much in it's Baker Jardine days- one good in house correlation, but not much else.
#Pipesim sim simulator
What you want is a compositional single phase simulator such as pipeflo, pipesim etc. It's phenomonally expensive (or was, when I was in pipeline design!) I agree with zdas- OLGA is way, way over the top for what you want to do- OLGA is more for single and (especially) multi phase transient behaviour.
