摘　　要：随着温室效应加剧,CO_(2)减排行动已迫在眉睫。水合物法分离CO_(2)工艺作为一种发展前景广阔的新型CO_(2)分离技术,为CO_(2)减排提供了一种解决思路。水合物法分离CO_(2)工艺相比于化学吸收、物理吸附、深冷分离和膜分离等技术具有分离效率高、过程简单无副产物、条件温和的优势,为减缓CO_(2)排放增加对环境造成的影响提供了一个中短期解决方案,以此为前提将允许人类继续使用化石燃料直至可再生能源技术广泛应用。本文综合分析了国内外的相关文献,介绍了水合物法分离CO_(2)工艺的基本原理,并比较了水合物法分离CO_(2)不同工艺的优劣之处,为进一步优化水合物法分离CO_(2)工艺提供指导。As the greenhouse effect caused by the increase of CO_(2) in the air is more and more serious,it is imperative to reduce CO_(2) emission.The technology of hydrate-based CO_(2) separation for CO_(2) emission reduction is a new CO_(2) separation technology with broad development prospects.Compared with the conventional technologies of chemical absorption,physical adsorption,cryogenic separation and membrane separation,the hydrate-based CO_(2) separation process has the advantages of high separation efficiency,simple process without by-products,and mild conditions.The technology of hydrate-based CO_(2) separation provides a short-term and medium-term solution for mitigating the impact of increased CO_(2) emissions on the environment,and will allow humans to continue to use fossil fuels until renewable energy technologies are widely used.In this paper,the basic principles of hydrate-based CO_(2) separation process were introduced,the advantages and disadvantages of different processes were also compared,and guidance for the further optimization of hydrate-based CO_(2) separation process was provided.
