Abstract

Abstract: To study the desulfurization performance of methyldiethanolamine(MDEA)+monoethanolamine(MEA)and MDEA+diethylenetriamine(DETA) mixed amine solution and provide formula and basic data for industrial gas desulfurization,a small reaction kettle was used to conduct the absorption testing. The impact of absorption temperature,absorption pressure,and regeneration temperature on the performance of amine solution removing H₂S was investigated using single methyldiethanolamine(MDEA)amine solution. The experimental results showed that the optimal absorption temperature is 50℃,the optimal absorption pressure is 5MPa,and the optimal regeneration temperature is 125℃. Based on the optimized process parameters,the effect of different annexing agents to amine solution on the absorption and regeneration performance was investigated. The results showed that adding diethylenetriamine(DETA)and monoethanolamine(MEA)to the single MDEA amine solution helped improve the absorption efficiency but had a negative effect on the regeneration. The optimized formulation is 2.4mol/L MDEA+0.6mol/LMEA,2.4mol/L MDEA+0.6mol/L DETA mixed amine solutions.

摘要： 为了研究以N-甲基二乙醇胺（MDEA）为主体的MDEA+一乙醇胺（MEA）和MDEA+二乙烯三胺（DETA）两种配方混合胺液脱除H₂S性能，给工业中天然气脱硫配方提供参考和基础数据。利用小型反应釜进行吸收实验，使用单一MDEA胺液进行了工艺参数的筛选，同时考察吸收温度、吸收压力、再生温度对胺液脱除H₂S性能影响，得出升高吸收温度、吸收压力均可在一定程度内提升MDEA胺液的H₂S吸收效果，但当吸收温度过高时会降低胺液的H₂S吸收效果，吸收压力过高会造成脱硫成本的增加，筛选出最优吸收温度50℃，吸收压力5MPa，解吸油浴温度125℃。在优选出的实验工艺参数条件下进行不同添加剂对MDEA胺液脱除H₂S性能影响研究，考察不同配比的MDEA+DETA混合胺液和MDEA+MEA混合胺液脱除天然气中H₂S吸收及解吸性能。通过分析不同配比胺液的吸收负荷、吸收速率及解吸率等指标得出，MDEA单一胺液中添加二乙烯三胺（DETA）、一乙醇胺（MEA）胺液均可提升其H₂S吸收性能但并不利于胺液H₂S解吸性能的提升。性能较优配方为2.4mol/L MDEA+0.6mol/L MEA、2.4mol/L MDEA+0.6mol/L DETA混合胺液。
