摘要
阐述了目前基于添加剂环境下水合物法分离烟气中CO2的研究进展,主要对烟气水合物热力学、动力学、分离效果3个方面的研究状况进行了总结。重点对当前应用于烟气体系研究较多的几类添加剂——四正丁基溴化铵(TBAB)、四氢呋喃(THF)、环戊烷(CP)的性质、原理、优势及不足进行了介绍和对比,对一级水合物法处理烟气的研究现状进行了分析和评价,并预测了有效提高水合物法分离效果的可行方法。
In this paper, the recent development of capturing carbon dioxide ( CO2 ) from flue gases using hydrate method under additive conditions are introduced. The hydrate thermodynamics, kinetics and separation effect in flue gas systems are summarized. The properties, principles and advantages of the most common additives such as tetra-n-butyl ammonium bromide ( TBAB ), tetrahydrofuran (THF) and cyclopentane (CP) are highlighted. An effective way of improving hydrate separation is suggested based on the above comparison and discussion of the recent research on CO2 recovery from treated flue gases by one stage of clathrate hydrate process.
