摘 要: 利用自制的气体水合物实验装置, 研究了瓦斯水合物在表面活性剂Tween-40 水溶液
(0.001 mol/L) 中的三次生成过程, 对水合物生成诱导时间、生成时温度、压力等参数之间的关系进行了分析, 将实验热力学结果与相平衡软件计算数据进行了比较, 结果表明,Tween-40 改变了瓦斯水合物生成的热力学条件。运用表面活性剂对水合物生成的物理作用理论阐述了这一现象的热力学机理。

Study on the Changed Effect of Tween-40on the Thermodynamics Conditionsof Gas Hydrate FormationWU Qiang, WANG Yong-jing, ZHANG Bao-yong(Heilongjiang Institute of Science&Technology, Ha ＇rbin150027China)Abstract:Utilizing self-developed experimental equipment of gas hydrate, three experimental processes of gas hydrate formation inTween-40 solution (0.001mol/L) were studied. Then the relations among induction time, formation temperature and pressure ofgas hydrate were analyzed, and the experimental thermodynamics data were compared with the calculations of Phase EquilibriumSoft, the results indicated that Tween-40 had changed the thermodynamics conditions of gas hyd
