摘要
提出使用高性能的氟碳表面活性剂来促进天然气水合物的生成,并通过实验研究了氟碳表面活性剂、碳氢表面活性剂及其复配后的表面活性性能,分析了配比、浓度和温度对复配溶液表面张力的影响,提出相应的表面张力计算关联方法。最后分析研究了压力对天然气水合物溶液表面张力的影响,提出利用等张比容法(基团贡献法)计算表面张力。此研究为表面张力对天然气水合物形成的影响提供一定的研究基础。
The fluorocarbon surfactant was introduced to promote natural gas hydrate formation.Surface activity of the fluorocarbon surfactant,hydrocarbon surfactant and their mixture was studied by experiment,the effects of the component ratio,concentration and temperature on the surface tension of the mixed surfactant were analysed and calculation methods for its surface activity were proposed.Effects of pressure on the surfactivity of natural gas hydrate solution were also studied and parachor method（i.e.group contribution method） was proposed for calculating its surface tension.The study provided a foundation for research on the effects of surface tension on natural gas hydrate formation.
