MDEA复配胺液脱除天然气中H2S性能
Performance of MDEA mixed amine solution removal H2S from natural gas
摘要
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 resultsshowed 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.关键词
