摘要： 在热量分析和压力分析基础上设计了化学链制氧流程，采用流程模拟软件Aspen Plus进行模拟，分析了反应温度，压强对系统能耗的影响并对制氧流程进行优化.结果表明:常压运行时，随着制氧反应温度升高，能耗降低；随着氧化反应温度升高，能耗升高；两个反应器温差越小，能耗越低.负压运行时，随着制氧反应器压强的降低，能耗降低；正压运行时，随着氧化反应器压强的增加，系统能耗呈先降低后升高的趋势.依据上述研究结果，得到了制氧反应器负压运行、氧化反应器正压运行系统的优化操作参数.

Abstract: The chemical looping oxygen production system was designed based on thermal analysis and pressure analysis .Then Aspen Plus chemical process simulation software is used to simulate and analyze the influence of reactor temperature and pressure on system energy consumption in order to optimize the oxygen production system. The results show that under ordinary pressure with the increasing of oxygen reactor temperature the system energy consumption decreases; whereas with the increasing of oxidation reactor temperature the energy consumption increases; and also the smaller the difference of temperature between two reactors is， the lower the system energy consumption is. Under negative pressure with the decreasing of the pressure of oxygen reactor， the system energy consumption decreases. However， under positive pressure with the increasing of the pressure of oxidation reactor， the energy consumption first decreases and then increases. Therefore， the optimization of operating parameters can be obtained in the oxygen production system where oxygen reactor runs under negative pressure and oxidation reactor under positive pressure.

Key words: chemical looping oxygen production, process simulation, Aspen Plus, thermal analysis, pressure analysis, system energy consumption
