the adverse effect of sds on the growth rate of double tetra n-butylammonium chloride + methane semiclathrate hydrate

Gas hydrates could provide a clean and sustainable option to meet global energy demands. accelerating gas hydrate formation is crucial to exploiting its positive applications, as these ice-like structures can serve as a vast and clean source of energy. in this research, we delve into the influence of sodium dodecyl sulfate (sds) on the growth rate of double tetra n-butylammonium chloride (tbac) + methane semiclathrate hydrate. to investigate this, we conducted experiments utilizing a stirred batch cell with a total volume of 169 cm3. the cell’s temperature was maintained at 278.15 k, while the initial pressures were set at 6 and 8 mpa. comparing the results with pure water, sds showed a significant positive effect on the growth rate of methane hydrate formation. however, when 400 ppm of sds was introduced, it had a detrimental impact on the average growth rate of the double (tbac + methane) semiclathrate hydrate within just 50 minutes of the process.
