N-甲基二乙醇胺和三乙烯四胺混胺吸收CO2性能的研究
Absorption of CO2 by Mixed Amine of N-Methyldiethanolamine and Triethylenetetramine
摘要
Abstract
Five absorbents with 30%(φ) mixed amine which was prepared fromN-methyl diethanolamine(MDEA) and triethylene tetramine (TETA) were used to absorb CO2 in self-made absorption/desorption experimental installation. The eff ects of ratio of MAEA to TEYA in the mixed amine and using times of the absorbents on their performances in the absorption of CO2 were studied. The experimental results showed that,the absorption/desorption performances of absorbentⅢ with MDEA of 26%(φ) and TETA of 4%(φ) were the best;under the condition of 101.33 Pa and 298.15 K the total CO2absorption was 0.869 9 mol/mol and average absorption rate was 1.880 mmol/s;under the condition of 101.33 Pa and 383.15 K, the CO2 desorption rate was 91.61%. After absorbentⅢ was used four times,the total absorption was decreased by 26.8% and the CO2desorption rate was decreased by 15.7%;the quality and pH of absorbentⅢ was reduced,but it still had fairly good absorption/desorption performances.关键词
