摘要

二氧化碳水合物技术在一系列成熟和新兴领域引起了越来越多的兴趣,包括海上油气流动保障、二次制冷、碳捕获和封存。在大多数这些应用中,二氧化碳水合物以浆料的形式存在,固体水合物颗粒分散在液体介质中。二氧化碳水合物浆料的流变和流动行为是其成功应用的关键。与天然气水合物相比,二氧化碳水合物的研究相对较晚。现有的综述主要集中在CO2水合物的热力学和形成动力学上,对流动相关性质的关注有限。为了解决这一差距,我们全面回顾了二氧化碳水合物浆体流动的四个关键领域:(1)流变学,(2)二氧化碳水合物与分散介质之间的界面张力,(3)流动建模,(4)实际应用。最后,我们讨论了当前的挑战和未来的研究方向。本综述提供的见解旨在支持高效和可扩展的二氧化碳水合物技术的发展。

CO2 hydrate slurry rheology, flow, and modeling: A comprehensive review

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.
