摘要
天然气水合物是一种类似冰的笼型晶体水合物。它的生成与压力、温度、气水接触面积以及添加剂等因素有关。利用天然气水合物储气实验台 ,实验研究了不同类型的表面活性剂 (包括阴离子表面活性剂、非离子表面活性剂 )对天然气水合物生成的影响 ,主要研究了它们对天然气水合物生成速度、储气密度、诱导时间以及虚拟水合数的影响。结果表明 :不同类型的表面活性都不同程度提高了水合物生长速度和储气密度 ,缩短了水合物形成的诱导时间 。
Natural gas hydrate is a cage-like crystalline compound similar to ice and its formation is related to these factors, such as pressure, temperature, water-gas contact area and additive, etc. By use of the experimental apparatus of natural gas hydrate, the effects of various surfactants, including anionic surfactant and non-ionic surfactant, on natural gas hydrate formation were experimentally researched, its generating rate, storage capacity, induction time and virtual hydrate number being maninly studied Through experiments it is indicated that various surfactants can raise its generating rate and storage capacity and shorten the induction time to a certain extent, and can make the virtual hydrate number approaching to the theoretical value.
