Özet

In this study, methane and gas mixture (including 88.17% propane) hydrates were produced from the anionic surfactant solutions of 0.00, 0.01 and 0.05 wt.% to investigate the effect of surfactant on the hydrate formation rate. Hydrate formation rate increases (promotion effect) with surfactant concentration, but the extent of the surfactant effect is closely related with the type of hydrate structure. The increase in the hydrate formation rate of sII type structure is relatively small compared to that obtained with structure sI. (C) 2002 Elsevier Science B.V. All rights reserved.
