Hydrate Formation Using Dowfax Gemini Surfactants
"Gas hydrate formation is a stochastic and slow process. However, the use of a small amount of surfactant can speed up the rate of hydrate formation. This work investigates the effect of two Dow surfactants, Dowfax 2A1 and Dowfax C6L, on gas hydrate formation, first by determining the adsorption …
