Experimental Study of the Effect of Non-ionic Surfactants with Different Molecular Weights on Inhibition of Ethane Gas Hydrate Formation

In this work, experimental investigation of the effect of the nonionic surfactant lauryl alcohol ethoxylate and EO/PO copolymers with different molecular weights on the amount of inhibition of ethane gas hydrate formation was conducted. For this purpose, measurement of the induction time and study of the kinetics of ethane gas hydrate formation were performed in the presence of various molecular weights of these additives at 21 bar pressure and temperature of 277 K. The results achieved determine the best molecular weight for increasing the induction time by the two additives.
