Depressurizing from supercritical conditions

asked Apr 13, 2015 in Simulation by RichS29 (4,320 points)


Can you suggest me a depressurizing program which can handle the supercritical fluid appropriataly. I need to depressurize risers containing reservoir fluid from high pressures (above 400 bar) and temperatures between 5 °C to 90 °C to 50% of the riser design pressure in 15 minutes.

I was wondering if there is a program to simulate this very specific problem. I have been using Hysys depressuring utility but in supercritical regions there are issues with phase inversion leads to the faulty results and very unstable simulation model.
