Dual Function Gas Hydrate Inhibitors

UW ID: 08-062

Description of Technology

The present technology inhibits clathrate hydrate formation by adding ionic liquids that are soluble in water. Ionic liquids are liquid organic slats that have strong electrostatic charges and, at the same time, their anions and/or cations can be chosen or tailored to form hydrogen bonding with water. Due to their strong electrostatic charges and hydrogen bond with water, they are able to act as both thermodynamic and kinetic inhibitors if carefully tailored for this purpose.


Dual Function Gas Hydrate Inhibitors are useful for the production, processing and transportation in the oil and gas industry, especially for deep-sea exploration and production where the operating temperature and pressure are favorable for hydrate formation.

Features & Benefits

The primary features of Dual Function Gas Hydrate Inhibitors could shift the hydrate-aqueous liquid-vapor equilibrium (HLVE) curve to a lower temperature and also retard the hydrate formation by slowing down the hydrate nucleation process. The most significant benefit of this technology is an increase in operational safety by preventing formation of gas hydrates while remaining an economically viable solution.
