TEA-DETA混合胺水溶液吸收CO_2的研究

Absorption of Carbon by TEA-DETA Blended Amine

采用圆盘塔 ,对TEA(三乙醇胺 )与DETA(二乙烯三胺 )混合水溶液吸收CO2 进行了研究。实验在常压下、温度 30 3～ 333K ,混合胺浓度 0 75～ 3 0 0kmol·m-3 的条件下对吸收量、吸收速率进行了测定 ,并与其它混合胺进行了比较 ,证明DETA(二乙烯三胺 )

The absorption of carbon dioxide into blended amine equeous solution of TEA and DETA was studied in a disc column circulating liquid flow.The experiment deterimined the absorption rate and quantity under 1 atm,303～333K and 0 75～3 00 kmol·m -3 of blended amine.It was compared with other blended amine and testified that DETA was a good activator.
