APPLICATION OF CARBONATES AND THEIR DERIVATIVES IN FORMULATIONS FOR GAS HYDRATE INHIBITORS

In gas hydrate inhibitor formulations used to prevent or inhibit the formation of gas hydrates in multi-phase fluids, such as hydrocarbon production fluids, conventional solvents can be largely replaced by at least one organic carbonate solvent, such as ethylene carbonate, propylene carbonate, and/o...

Beschreibung
Zusammenfassung:	In gas hydrate inhibitor formulations used to prevent or inhibit the formation of gas hydrates in multi-phase fluids, such as hydrocarbon production fluids, conventional solvents can be largely replaced by at least one organic carbonate solvent, such as ethylene carbonate, propylene carbonate, and/or glycerol carbonate. The gas hydrate inhibitors in these formulations may be, but are not necessarily limited to, polyesteramides, polyvinylpyrrolidones, and the like. The use of an organic carbonate in the gas hydrate inhibitor formulation can improve the capability of the formulation for inhibiting or preventing gas hydrate formation in a multi-phase fluid. L'invention concerne des formulations d'inhibiteur d'hydrates de gaz utilisées pour empêcher ou inhiber la formation d'hydrates de gaz dans des fluides à phases multiples, tels que des fluides de production d'hydrocarbures, dans lesquelles les solvants classiques peuvent être largement remplacés par au moins un solvant de carbonate organique, tel que le carbonate d'éthylène, le carbonate de propylène et/ou le carbonate de glycérol. Les inhibiteurs d'hydrates de gaz dans ces formulations peuvent être des polyesteramides, des polyvinylpyrrolidones, et analogues, mais ne sont pas nécessairement limités à ceux-ci. L'utilisation d'un carbonate organique dans la formulation d'inhibiteur d'hydrates de gaz peut améliorer l'aptitude de la formulation à inhiber ou à enpêcher la formation d'hydrates de gaz dans un fluide à phases multiples.
