2-2-2 Evaluation method for the effect of kinetic inhibitors for growing or melting tetrahydrofuran clathrate hydrate

Abstract

We study the formation or melting process of tetrahydrofuran (THF) clathrate hydrate from polyvinylpyrrolidone (PVP), or polyvinyl alcohol(PVA) aqueous solution as a function of growth rate V and adsorbed KHIs concentration c using the unidirectional growth technique. We have already reported the evaluation method for growth inhibition performance of KHIs for the clathrate hydrate–aqueous solution system. This study aims to evaluate various type of KHI performances, and test the same method for evaluating the dissociation inhibition effect of KHIs on melting hydrate crystals.
