Process for transporting gas hydrates formed from a natural gas or from a condensate gas, consisting in using a dispersing additive, possibly coupled with a film-forming additive, in solution in a liquid hydrocarbon fraction, this liquid hydrocarbon fraction participating in the formation of an emulsion and/or of a suspension with the condensation water produced and the hydrates. The dispersing additive is recycled after the transportation of the hydrates in the pipe.

[ We claim:] [1.] A process for transporting in a pipe a fluid containing at least a gas phase and water, under conditions where hydrates may form from the water and the gas, the fluid being a dry gas or having a high GLR value such that an amount of condensate of a liquid hydrocarbon phase is insuf

[ We claim:] [1.] A process for transporting in a pipe a fluid containing at least a gas phase and water, under conditions where hydrates may form from the water and the gas, the fluid being a dry gas or having a high GLR value such that an amount of condensate of a liquid hydrocarbon phase is insufficient to transport the hydrates, the process comprising incorporating in the fluid a mixture comprising a liquid hydrocarbon fraction and a dispersing additive in solution in the liquid hydrocarbon fraction, the amount of liquid hydrocarbon fraction being selected so that the liquid hydrocarbon/liquid water ratio ranges between 1 and 20, whereby the dispersing additive disperses the water and hydrates in the liquid hydrocarbon faction.
