CO2 hydrates are a nuisance in the petroleum industry but also constitute a great opportunity as they form the basis for a new technology for capturing CO2 from flue gases. Both the understanding of the problems caused by them and the exploitation of CO2 hydrates require high quality experimental thermodynamic data and rigorous models which can be used over an extensive range of conditions and chemicals (used as gas hydrate formers and inhibitors).

The objectives of the project is to build a solid experimental and theoretical framework for fully understanding and addressing the problems of CO2 hydrates in the petroleum industry and for enhancing the future utilization of hydrate crystallization as a CO2 capture technology.

Two research groups from DTU (Denmark) and Ecole des Mines (France) will closely work towards the above objective. More specifically, new experimental data will be produced for the gas hydrate formation from mixtures of CO2 + N2 + water (and THF aqueous solution). For the modeling of these and literature data, a novel theory, based on statistical thermodynamics, will be developed for both the description of solid and fluid phases and applicable to a wide range of conditions and chemicals (hydrate formers and hydrate inhibitors).
