The kinetics behavior of methane hydrate formation in the presence of tetrahydrofuran(THF)as promoter was studied.A set of experimental equipment was designed and constructed.A series of kinetics data for the formation of methane hydrate in the presence of THF were measured with the isochoric method.The influences of temperature, pressure and liquid flow rate on the methane consumption rate were studied respectively.Based on the Chen-Guo hydrate formation mechanism,a kinetics model for the formation of methane hydrate in the presence of THF by using the dimensionless Gibbs free energy difference of quasi-chemical reaction of basic hydrate formation,??GRT,as the driving force was proposed.The model was used to calculate the rate of methane consumption and it was shown that the calculated results were in good agreement with the experimental results. A kinetic data for the formation of THF hydrate in the presence of THF were studied with the isochoric method. These influences of temperature, pressure and liquid flow rate on the methane consumption rate were scaled respectively.Based on the Chen-Guo hydrate formation mechanism, a kinetics model for the formation of methane hydrate in the presence of THF by using the dimensionless Gibbs free energy difference of quasi-chemical reaction of basic hydrate formation, ?? GRT, as the driving force was proposed to the rate of methane consumption and it was shown that the calculated results were in good agreement with the experimental results.
