Experimental studies and modeling of kinetics for methane hydrate formation with THF promoter in bubble column

The kinetics of CH₄ hydrate formation with the presence of hydrate promoter THF was studied in a transparent bubble column.The effects of gas flow rate, temperature, pressure and volume fraction of hydrate on formation rate were measured.Based on the Chen-Guo hydrate formation mechanism, by using the simplified Gibbs free energy change of quasi-chemical reaction to form basic hydrate,-ΔG/RT, as the driving force, a kinetic model which took account of system temperature, pressure and specific gas-liquid interfacial area was established.The model was used to calculate the consumption rate of CH₄ and the predicted results were in agreement with the experimental data.The experimental results and the kinetic model in this work would be helpful to designing commercial hydration reactor and optimizing operation conditions.
