Conventional temperature swing adsorption (TSA) is mainly applied for the removal of trace contaminants. Indirectly heated and cooled adsorbers were developed to make bulk separation economically feasible. A quasi‐continuous TSA process to remove CO₂ from an N₂/CO₂ mixture with a pilot plant is established. The experimentally determined data are taken to validate and to adjust a 2D simulation model. For the validation, the CO₂ desorption, the N₂ recovery rate as well as the axial temperature profile are compared. The successful model validation can be seen in the good agreement between simulation and experimental results. Moreover, this process is able to separate high amounts of CO₂ and to produce a nearly CO₂‐free product stream.

间接温度波动吸附单元多维模型的实验验证

常规的变温吸附（TSA）主要用于去除痕量污染物。开发了间接加热和冷却的吸附器，以使本体分离在经济上可行。建立了中试工厂从N ₂ / CO ₂混合物中去除CO ₂的准连续TSA工艺。实验确定的数据用于验证和调整2D仿真模型。为了验证，比较了CO _2的解吸，N _2的回收率以及轴向温度曲线。在仿真和实验结果之间的良好一致性中可以看到成功的模型验证。此外，此过程能够分离大量的CO ₂并产生几乎不含CO _2的产品流。
