Kinetic study of CH4 hydrate formation in the presence of tetrabutylphosphonium chloride (TBPC)
Methane hydrate is considered as an excellent choice for transporting and storing natural gas. To improve the hydrate formation conditions, adding semiclathrate hydrate formers was strongly recommended. The major objective of this study was to investigate formation kinetics of tetrabutylphosphonium...

Methane hydrate is considered as an excellent choice for transporting and storing natural gas.
