Correlation of Hydrate-Film Growth Rate at the Guest/Liquid-Water Interface to Mass Transfer Resistance

Abstract

The correlation of hydrate-film growth rate at the guest/liquid-water interface to mass transfer limitations is considered. Most of the hydrate-film growth rate data from the literature are compiled based on the system subcooling (ΔT), suggesting predominant heat transfer limitations. In this communication, we investigate how existing data on hydrate-film growth is better correlated to solubility differences of the guest species in equilibrium with bulk fluid and hydrate.
