I would like to know what software to use too! For blowdown, I was wondering about using the Hysys Depressure Utility. You don't need the dynamic license to run this, just the regular Hysys license. However, Hysys probably won't predict solid CO2 very well so it might not be that realistic. And...
Thanks David,
I see that the boiling of the liquid is the main concern here in that it will reduce the temperature of the pipe.
I wonder if people who have done this sort of thing have done it in stages and used "waiting periods" in between to allow the soil around the buried pipeline to warm...
Hello all,
My first post so please be kind! I am looking at how to blowdown a CO2 pipeline with the following conditions;
16" diameter
20 mile section to be depressured
operating pressure: 2200 psia
temperature: 50F (buried pipeline)
Phase: I beleive that since I'm below the 88F critical...
