CO2 hydrate slurry rheology, flow, and modeling: A comprehensive review
CO2 hydrate technology is attracting growing interest across a range of established and emerging fields, including offshore oil and gas flow assurance, secondary refrigeration, and carbon capture and sequestration. In most of these applications, CO2 hydrates exist in the form of a slurry, with solid hydrate particles dispersed in a liquid medium. The rheological and flow behaviors of CO2 hydrate slurries are critical to their successful applications. Compared to natural gas hydrates, CO2 hydrate research is relatively recent. Existing reviews primarily focus on thermodynamics and formation kinetics of CO2 hydrate, with limited attention to flow-related properties. To address this gap, we present a comprehensive review of four key areas central to CO2 hydrate slurry flow: (1) rheology, (2) interfacial tension between CO2 hydrate and the dispersion medium, (3) flow modeling, and (4) practical applications. We conclude with a discussion of the current challenges and future research directions. The insights provided in this review aim to support the development of efficient and scalable CO2 hydrate technologies.
