Abstract

Abstract : We present the first quantitative measurements of hydrate formation probability, nucleation rate and growth on a water droplet suspended within a high pressure natural gas by acoustic levitation. Abstract : Hydrate formation was studied using water droplets acoustically levitated in high-pressure natural gas. Despite the absence of solid interfaces, the droplets' area-normalised nucleation rate was about four times faster than in steel autoclave measurements with interfacial areas roughly 200 times larger. Multiple stages of stochastic, template-free hydrate growth were observed.
