Gas hydrates are a type of ice that incorporate simple gas molecules into their crystal structures. Formed under the application of moderate pressure, these inclusion compounds occur widely in nature and also have importance for the oil and gas industry. They are of additional interest where the systems are valuable for studying fundamental water-water and water-guest interactions. The existence of CO2 hydrate is well known and it has potential applications in carbon capture and storage, however the system is not yet fully understood. There is presently an unsolved hydrate phase at 0.7 GPa and the system exhibits a high pressure behaviour which departs from what is observed in other similar systems. In this talk I will present the results of an investigation into possible hydrates phases in the system above 1 GPa, as well as the present status of efforts to solve the phase at 0.7 GPa.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
