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 hydrate formation, the mechanism ofwhich was expatiated by the theory of surfactant��s physical effect on the process of gas hydrate formation.Key words:coal and gas outburst; gas hydrate; surfa
