another report made by brinchi and co 2001 showed the hydrate of methane can form by introducing water in a flowing gas at a pressure and temperature of about 120 bar and 34°c respectively. this ensures that no liquid water leftover occurs after the hydrate is formed but stores low amount of CH4 in the hydrate. surfactant used in his experiment was sodium dodecyl sulphate at a concentration of 250 500ppm and it reduced the rate of formation of hydrate to about thirty five minutes brinchi et al 2001 .there are several forms which the hydrate of natural gas 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 H2O and gas at large pressures and low heat they all have their advantages disadvantages and distinct techniques. different surfactants were used to carry out the formation of hydrates but rajnauth et al 2012 reported that the best surfactant that improved the reaction rate of hydrate was sodium dodecyl sulphate.
