| 摘 要： | 针对高炉煤气吸收法脱碳富集,实验研究了复合有机胺溶液对CO2的解吸特性。分别研究了吸收CO2达到饱和的二元复合有机胺DEA-DETA、DEA-TETA、MDEA-DETA、MDEA-TETA溶液的解吸曲线。结果表明,与DEA溶液相比,DEA-DETA溶液解吸速率峰值提高约33.6%,对应的解吸温度下降约4℃;DEA-TETA溶液解吸速率峰值提高约26.8%,对应的解吸温度相近。与MDEA溶液相比,MDEA-DETA溶液在70.1~77.8℃温度区间内解吸速率有所提高,MDEA-TETA溶液在66.9~90℃温度区间内解吸速率有所提高。4种复合有机胺溶液的解吸速率峰值分布为:7.533mL/s(MDEA-TETA)6.806mL/s(MDEA-DETA)5.603mL/s(DEA-DETA)5.317mL/s(DEA-TETA);解吸速率峰值对应的解吸温度分布为:90.3℃(DEADETA)90.9℃(MDEA-DETA)91.8℃(MDEA-TETA)94.6℃(DEA-TETA)。

| Abstract: | In order to concentrate blast-furnace (BF) gas by adsorption, an experimental study on the CO2 desorption characteristics of complex organic amine was carried out. Four kinds of complex organic amine solutions, for example DEA-DETA, DEA-TETA, MDEA-DETA, MDEA-TETA, were investigated. The experiment results show that, comparing with the DEA-solution, the complex solution of DEA-DETA owns higher maximum-desorption-rate with a promotion of 33. 6% and lower corresponding desorption temperature with a decrement of about 4??; the complex solution of DEA-TETA has higher maximum-desorption-rate with a promotion of 26. 8% and similar corresponding desorption temperature. Comparing with MDEA-solution, both of MDEA-DETA and MDEA-TETA have higher desorption-rate when their temperatures are respectively between 70. 1-77. 8 and 66. 9-90??. The results also show that, the maximum-desorption-rates of those solutions are in order of 7. 533mL/s (MDEA-TETA)??6. 806mL/s (MDEA-DETA)??5. 603mL/s (DEA-DETA)??5. 317mL/s (DEA-TETA); the corresponding desorption temperatures are in order of 90. 3?? (DEA-DETA)??90. 9?? (MDEA-DETA)??91. 8?? (MDEA-TETA)??94. 6?? (DEA-TETA). |
