A process for delaying the formation and/or reducing the agglomeration tendency of hydrates in conditions under which a hydrate may be formed, these hydrates being formed from water and gas. The process according to the invention wherein, in particular, an additive comprising at least one amphiphilic compound chosen from the group of esters of polyols and substituted or unsubstituted carboxylic acids is used. Application of the process according to the invention to processes using gases and water, which form hydrates between them, in particular in the petroleum or gas industry.

Process for delaying the formation and/or reducing the agglomeration

Process for extraction of water mixed with a liquid fluid

The invention concerns a process for delaying the formation and/or reducing the agglomeration tendency of hydrates in conditions under which a hydrate may be formed, these hydrates being formed from water and gas. The process according to the invention wherein, in particular, an additive comprising at least one compound from the group of hydroxycarbylamides of substituted carboxylic acids is used. Application of the process according to the invention to processes using gases and water, which form hydrates between them, in particular in the petroleum or gas industry.

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.
