摘要

盐穴储氢是实现大规模、长周期储氢的重要技术途径，但采出气中常含有CO

、H

S、H

O、CH

和N

等杂质，导致采出氢纯度难以满足氢燃料电池行业对氢气纯度的严格要求。因此本研究提出了“净化-提质”集成工艺路线，并采用Aspen Plus对不同工艺路线进行了模拟与优化。净化阶段分别采用乙醇胺（MEA）和甲基二乙醇胺（MDEA）化学吸收脱酸工艺以及三甘醇脱水（TEG）和低温分离脱水工艺；提质阶段分别采用膜分离、变压吸附和有机液储放氢（LOHC）提质工艺对净化后的氢气进行深度提纯，并对膜分

离及有机液储放氢提质在模拟工况下进行了实验可靠性验证。模拟结果表明，净化单元可将氢气纯度由95%提升至99%，其中MDEA吸收法和低温分离法在能耗及技术经济性方面分别优于MEA吸收法和三甘醇脱水法。三种提质工艺均可将氢气纯度进一步提升至99.99%以上，膜分离及有机液储放氢提质实验结果证实了模拟结果的可靠性。提质工段的变压吸附工艺氢气回收率最高且能量负荷最低，膜分离工艺能耗主要集中在压力输送设备，有机液储放氢提质工艺受脱氢吸热反应影响能耗最高。综合比较不同净化与提质组合工艺后发现，“MDEA吸收-低温分离-变压吸附”工艺路线综合性能最优。

Abstract

Salt cavern hydrogen storage represents a critical technological approach for large-scale and long-duration hydrogen storage. However

the produced gas commonly contains impurities such as CO

and N

making the purity of recovered hydrogen fail to meet the stringent requirements of hydrogen fuel cell industries. Accordingly

this study proposes an integrated "purification and upgrading" process scheme and conducts simulation and optimization of various process routes via Aspen Plus. In the purification stage

chemical acid gas removal processes using monoethanolamine (MEA) and methyldiethanolamine (MDEA) are adopted

along with dehydration technologies including triethylene glycol (TEG) dehydration and low-temperature separation dehydration. In the upgrading stage

membrane separation

pressure swing adsorption

and liquid organic hydrogen carrier (LOHC) upgrading processes are applied for deep purification of the pre-purified hydrogen. Experimental verification is also performed to validate the reliability of the simulation results for membrane separation and LOHC upgrading under simulated operating conditions. Simulation results reveal that the purification unit can raise hydrogen purity from 95% to 99%. Specifically

MDEA absorption outperforms MEA absorption

and low-temperature separation is superior to TEG dehydration in terms of energy consumption and technical economy. All three upgrading processes can further increase hydrogen purity to above 99.99%. Experimental data from membrane separation and LOHC upgrading confirm the validity of the simulation outcomes. Among the upgrading sections

pres

sure swing adsorption achieves the highest hydrogen recovery rate and the lowest energy load. The energy consumption of membrane separation is mainly attributed to pressure conveying equipment

while LOHC upgrading presents the highest energy consumption due to the endothermic dehydrogenation reaction. A comprehensive comparison of different combined purification and upgrading processes indicates that the integrated route of MDEA absorption

low-temperature separation

and pressure swing adsorption delivers the optimal overall performance.
