胺基碳捕集工艺过程中VOCs排放与迁移

ANALYSIS OF EMISSION AND DIFFUSION OF VOCs FROM AMINE-BASED POST-COMBUSTION CO_2 CAPTURE

胺基碳捕集工艺是燃烧后CO_2捕集的主要方法,是目前工业上降低CO_2排放的有效措施,但会导致其他污染物的排放,如胺溶剂蒸发、降解产物(硝胺、亚硝胺等)挥发性有机化合物(VOCs)的排放。在总结前人研究成果基础上探讨了胺基碳捕集工艺释放VOCs的排放过程,对VOCs扩散与迁移模型进行系统总结和分析,为CO_2捕集工程的安全设计和环境评价提供可借鉴的经验与思路。

Amine solvents are usually the effective measures in post combustion CO_2 capturing to reduce greenhouse gas emissions,but it can lead to emission of some other pollutants,such as volatile organic compounds（ VOCs）,including amine solvents evaporation or degradation products（ nitrosamines and nitramines,etc.）. On the basis of the former researches,this paper aimed to investigate nitrosamines and nitramines emission and diffusion from the amine-based post-combustion CO_2 capture,in order to provide experiences and idea for safety design and environment evaluation of CO_2 trapping engineering cases.
