Another report by Brinchi and Co

Another report by Brinchi and Co (2001) showed that methane hydrate could be formed by introducing water in a flowing gas at a pressure and temperature of about 120 bar and 3 – 4°C respectively. This method ensures that there is no liquid water leftover after the hydrate is formed but stores a low amount of methane in the hydrate. The surfactant used in his experiment was sodium dodecyl sulphate at a concentration of 250 – 500ppm and it reduced the rate of hydrate formation to about thirty five minutes (Brinchi et al, 2001).
There are several forms which Natural gas hydrate can be produced. Some of them are as pellets, icy solid masses, dry powdery snow like flakes, or as slurry. Although they all use the general process of mixing water and gas at high pressures and low temperature, they all have their advantages, disadvantages and special techniques. Different surfactants have been used to carry out the formation of hydrates but Rajnauth et al, (2012) reported that the most effective surfactant that improved the production rate of hydrate was sodium dodecyl sulphate.
