| 摘 要： | 二氧化碳捕集与封存（CCS）各工艺过程的设计、运行都依赖于对CO2及其混合物热物理性质的深入理解。同时,CCS的规模化发展和商业化进程,对CO2混合物及其热物性的准确性提出了更高的要求。本文从实验数据、理论模型和典型应用3个方面综述了CO2及其混合物热物性的发展现状,并尝试对发展趋势进行归纳。在实验研究方面,CO2混合体系的研究进展视组分不同,差异较大,其中CO2-N2、CO2-CH4、CO2-H2O和CO2-H2二元体系已形成较完善的物性数据库,而CO2-NH3、CO2-NO x 和CO2-CO体系的物性数据还比较欠缺;在物性估算方面,面向CCS的物性估算模型研究自2008年开始活跃,基于不同理论构架,目前已逐步形成面向CCS的多元化的物性估算体系。物性研究在CCS中的应用主要体现在物性是支撑CCS过程研究的基础,其不准确性在过程模拟或计算中会被“放大”,从而影响过程评估的准确性,本文从物性在循环构建和能效分析中的作用以及CO2水合物的形成3个方面入手做了说明。文章最后对面向CCS的物性研究趋势进行了梳理,对分子模拟技术、通用性强的物性估算模型和物性在过程设计和循环分析中的角色进行了展望。

| Abstract: | Thermodynamic properties of CO2 mixtures play a critical role in the whole chains of carbon capture and storage (CCS) process. In recent years, the rapid development of CCS technology and its scale-up and commercial applications issue new challenges to the research of CO2 mixtures. In this paper, a literature review survey was conducted to identify the knowledge gap and the research progress of thermodynamic properties in terms of available experiment data, theoretical models and typical applications. In experimental aspect, there was great difference in the available data for different CO2 mixture systems. In particular, there were many available experimental data for the CO2-N2, CO2-CH4, CO2-H2O and CO2-H2 mixture systems while few data were available for CO2-NH3, CO2-NO x and CO2-CO systems. The study about the equations of states (EOS) became active since the year of around 2008. Based on different theory frameworks, many EOSs were further developed focusing on the application for CCS. In application aspect, the impact of thermodynamic properties on typical CCS process, thermodynamic cycle analysis as well as formation of CO2 hydrates were further reviewed and summarized. Finally, it was attempted to summarize several potential research directions of thermodynamic properties in CCS including development of property estimation methods with both EOS and molecular simulation as well as the roles of thermodynamic properties in process and thermodynamic cycle analysis. |
