Abstract
A method is provided for transporting in a duct a fluid comprising gas and water, and being under conditions where at least one hydrate is formed, the hydrates being formed from said gas and said water, wherein, before or during the formation of the hydrate or hydrates, an additive is injected into said fluid for reducing the tendency to agglomeration of the hydrate so as to obtain one or more hydrates in dispersed form, and said fluid is transported containing said hydrate or hydrates in dispersed form.

A method of transporting in a duct a fluid comprising gas and water, and being under conditions where at least one hydrate is formed, the hydrates being formed from said gas and said water, wherein, before or during the formation of the hydrate or hydrates, an additive is injected into said fluid for reducing the tendency to agglomeration of the hydrate so as to obtain one or more hydrates in dispersed form, and said fluid is transported containing said hydrate or hydrates in dispersed form.
A method of transporting a fluid comprising gas and water in a duct, said fluid being under conditions where at least one hydrate is formed, the at least one hydrate being formed from said gas and said water, wherein, before or during the formation of the at least one hydrate, an additive is injected into said fluid for reducing the tendency of the at least one hydrate to agglomerate so as to obtain at least one hydrate in dispersed form, and said fluid is transported containing said at least on hydrate in dispersed form;
- said additive comprises at least two amphiphilic compounds, the first of these compounds being an anionic amphiphilic compound, the second of these compounds being a non ionic amphiphilic compound.
A method of transporting a fluid comprising gas and water in a duct, said fluid being under conditions in which at least one hydrate is formed from said gas and water, which comprises injecting at least one additive into said fluid before or during formation of the at least one hydrate for reducing the tendency of the at least one hydrate to agglomerate and to obtain the at least one hydrate in a dispersed form within said fluid and transporting the fluid containing said at least one hydrate in dispersed form;
- said additive comprising at least one amphiphilic compound selected from the group consisting of a non-ionic amphiphilic compound, an anionic amphiphilic compound and a cationic amphiphilic compound.
