Span60对甲烷水合过程温度场影响的实验研究
Experimental study on effect of Span60 on temperature field in methane hydration process
摘要
Abstract
This paper is an effort to investigate the distribution characteristics and heat transfer law underlying the temperature field in the gas hydrate formation and decomposition process, together with the reaction heat and temperature field distribution in two systems.The investigation building on the experimental data and the equation for reaction heat calculation is focused on the calculation of the reaction heat in the two experimental systems;and the research into the effect of the addition of non-ionic surfactant sorbitan monostearate(Span 60) on the methane hydration reaction system temperature field.The results demonstrate that the addition of Span 60 enables an increase both in the number of methane hydrates and in the quantity of corresponding reaction heat, thereby increasing the temperature of the hydration reaction system and therefore the rate of temperature;and the analysis of the molecular structure of Span60 leads to the mechanism that Span60 could promote the methane hydration formation.The research could provide theoretical support for the application of gas hydrate solidification separation and storage and transportation technology.关键词
