With the successful application of kinetic hydrate inhibitors (KHIs) on plug prevention, there is a growing trend towards development affordable and environmentally friendly KHIs for solving challenges high cost inadequate biodegradability from their commercial KHIs. Therefore, further evaluation inhibitory effect developing needed under multiphase flow conditions. In this study, high-pressure, fully visible rocking cell were used to simulate transportation both considered. The results revealed that, given conditions PVCap exhibited excellent inhibition performance. Although pectin certain growth rate formation quantity, but it demonstrated strong promoting nucleation opportunities rates. However, sodium alginate, which shares similar characteristics with pectin, exerted significantly promotional effects in terms induction time, rate, water conversion. Furthermore, addition alginate led balls several test runs, resulting complete pipeline blockage. Another noteworthy discovery was relationship between final conversion hydrates, an initial increase followed by decrease, while time exhibits inverse trend, as velocity increased.
