摘要：

In this communication, experimental hydrate dissociation pressures for hydrogen sulfide+diethylene glycol (DEG)+water and hydrogen sulfide+triethylene glycol (TEG)+water systems are reported in the 276.8-288.3K and 271.3-289.5K temperature ranges for 0.05 and 0.15 mass fractions of DEG in aqueous solution and 279.0-289.9K and 276.9-290.6K for 0.05 and 0.15 mass fractions of TEG in aqueous solution, respectively. The experimental data were generated using an isochoric pressure-search method. The experimental hydrate dissociation data were compared with some selected literature data in the presence of pure water. In the concentration ranges studied in this work, it is shown that both DEG and TEG aqueous solutions have inhibition effects on hydrogen sulfide clathrate hydrates. Approximately the same inhibition effects are found for the DEG and TEG aqueous solutions studied in the presence work.
