以H2 S体积分数为2%的H2 S+CH4作为模拟天然气,在吸收温度50℃、吸收压力5 M Pa、解吸温度105℃的操作条件下,实验研究了三乙醇胺(T EA )与乙醇胺(M EA )以及三乙醇胺(T EA )与二乙烯三胺(DET A )摩尔配比为2、4、14的T EA+M EA、T EA+DET A两种混合胺液的 H2 S吸收与解吸性能,以吸收负荷、吸收速率、解吸率为指标筛选相对较优的混合胺液配方。结果表明,在实验范围内,TEA+ MEA混合胺液系列中, TEA/MEA摩尔比为2的T EA+M EA混合胺液具有最优的 H2 S吸收和解吸性能;T EA+DET A混合胺液系列中, T EA/DET A摩尔比为4的T EA+DET A混合胺液具有最优的H2 S吸收和解吸性能。与T EA/M EA摩尔比为2的T EA+ M EA相比, T EA/DET A摩尔比为4的T EA+DET A具有较高的 H2 S吸收速率与解吸率,综合脱硫效果较好。

With the mixture of H2S+CH4 as simulated natural gas ,in which the volume fraction of H2 S is 2% ,under the operating conditions of absorption temperature 50℃ ,absorption pressure 5M Pa , desorption temperature 105℃ , the H2 S absorption and desorption performance of triethanolamine(TEA)+monoethanolamine (MEA) and TEA+ diethylenetriamine (DETA) mixed amine solutions with TEA/MEA or TEA/DETA molar ratio of 2 ,4 and 14 , respectively ,were investigated .And the absorption load ,absorption rate and desorption rate were used as the indices to get the optimum ratio of mixed amine solution .The results showed that in the experimental range the TEA+MEA solution with TEA/MEA molar ratio of 2 in the series of TEA+MEA mixed amine solutions and the TEA + DETA solution with TEA/DETA molar ratio of 4 in the series of TEA + DETA solutions both possessed optimal H2 S absorption and desorption performance . Furthermore , the desulfurization performance of the TEA + DETA amine solution with TEA/DETA molar ratio of 4 was better than that of the TEA + MEA amine solution with T EA/M EA molar ratio of 2 .
