Abstract:

In this paper, the recent developments and applications of technologies of carbon dioxide removal  from the recycle stream of F-T synthesis are reviewed. Because of complicate composition of reaction gas, the process of carbon dioxide removal requires less-loss of useful gas，no side-reaction between solution and gases，and lower heat consumption. The new technologies of carbon dioxide removal from the recycle stream of F-T synthesis developed and applied by Research Institute of Nanjing Chemical Industry Group has the advantages of low hydrocarbon loss，stable solution，low heat consumption for solution desorption. The heat consumption for solution desorption is reduced by 30% than the conventional technology.

摘要：

介绍了反应循环气脱碳技术研究开发进展及各种最新应用。由于反应后的气体组成复杂，选择脱碳技术也有特殊要求，不仅要求有用气体损耗少、同时溶液不会因与气体成分接触发生降解，而且溶液再生热耗应尽可能降低。南化集团研究院研究开发的循环气脱碳技术的应用结果表明，其具有“有机组分损失低”、“溶液稳定性好”的优点，溶液再生热耗比常规的碳酸钾脱碳工艺降低30%以上。
