In view of the large energy consumption of the regeneration process in the chemical absorption decarburization process, on the basis of the enrichment classification flow process, the nanoscale ceramic film is used as a new heat exchanger between the enriched liquid and the regeneration gas. The porous ceramic film is capable of coupling thermal-ma...

... ceramic membrane tube selected in the experiment was purchased from Nanjing Aiyuqi Membrane Technology Co., Ltd., and packaged with the 304 stainless steel shell to form a single-channel ceramic membrane heat exchanger. Figure 1 shows a cross-sectional image of a ceramic membrane tube obtained by field emission scanning electron microscopy (SU-8010). It can be clearly seen from the figure that it is composed of three layers with different pore sizes, namely the support layer, the middle layer and the separation layer, which is consistent with the description of Chen et al. [19] , the pore size of the separation layer is the smallest, which is nanoscale, and the pore size of the support layer is the largest, which is micron level. ...
