相变浆液中甲烷水合物的生成过程强化
Enhancement of methane hydrate formation process in phase change slurry
摘要
Abstract
The phase change emulsion(PCE) containing phase change material(PCM) ofn-tetradecane was used to directly absorb heat of the hydration by the solid-to-liquid phase change ofn-tetradecane. Oncen-tetradecane in PCE was solidified in the hydrator, the PCE would convert to slurry. The impacts of different pressures from 5.0 to 6.28 MPa on the yield of methane hydrate and hydration rate in the slurry at the temperature 277.6 K were researched at a semi-batch hydrator. Considering the influence of methane dissolution inn-tetradecane on the hydration process, a PVT apparatus to measure the solubility of methane in liquidn-tetradecane was designed, and a more precise calculation process was established to describe the methane hydration. The results showed that:at low temperature conditions, the solubility of methane in liquidn-tetradecane distributed linearly versus pressure, and the methane hydrate formation process was intensified significantly compared to indirect heat removal hydration.关键词
