Liquid holdup in high pressure, low temperature, gas-condensate flow with low liquid loading including hydrate inhibitor

摘要

Gas-condensate pipelines with very low liquid drop out (Usl<0.005 m/s) are characterised by low rates of liquid accumulation in upward inclined sections. One particular feature of such flows in moderate upwardly inclined pipes is that there exists a region where the liquid holdup increases steeply with decreasing flow rate, To the authors knowledge, only very few data are presently available for these kind of systems which implies that present multiphase flow models to little extent have been tested for accuracy in this respect.
