Unlike other technologically relevant and in general well-described fluids such as aqueous mixtures, natural gas or refrigerants, carbon dioxide and its mixtures exhibit complex phase behavior involving vapor, supercritical fluid, CO2-rich liquid, water-rich liquid, and even solid phases such as dry ice and gas hydrates. As a result, the properties and phase behavior of CO2 systems can dramatically change even with a tiny variation of temperature, pressure or the mixture composition. Inappropriate design together with inaccurate detection of the system performance can result in serious failure of the CCS/U technologies such as pipeline blockage. Since carbon dioxide will not be in a pure state in any of the CCS/U technologies, the accurate description of thermophysical properties and phase behavior of its mixtures with components such as carbon monoxide, water, methane, argon, or hydrogen sulfide are of high demand. The water + carbon dioxide mixture is of special interest as it may form solids similar to water ice called clathrates or gas hydrates. The clathrates consist of water molecules arranged in a form of crystal structure and the gas molecules engaged inside the cavities of the crystal. The presence of gas molecules thermodynamically stabilizes the water crystal. The CO2 hydrates can form under CCS/U relevant conditions at temperatures below 20 °C and pressures above 10 bar. Our team has developed an accurate model of the CO2 hydrates that is being successfully used in the research and development of CCS/U technologies.
