Additively manufactured packed bed device for process intensification of CO2 absorption and other chemical processes

Effect of Manufacturing Techniques in Pressure Drop on Triple Periodical Minimal Surface Packings

“…Given the enhancement of process intensification achieved when moving from 1D packings to 2D packings, we also expect that when using three-dimensional arrays, better packing properties can be achieved. Additionally, such 3D designs can also be tailored for using them as mass transfer agents (like in absorption and distillation) or as heat transfer elements in reactors in completely different applications [8][9][10][11][12][13][14].…”

Advanced absorber heat integration via heat exchange packings

“…Typical overall heat transfer coefficients in industrial plate heat exchangers range from 150 to 15,000 W/m 2 K 59 . Miramontes et al have reported values ranging from 35 to 147.9 W/m 2 K for the heat exchange packings they have tested 29,28 . However, these heat exchange coefficients are in reference to the total geometric surface area of the packing, while h wall is in reference to the total wetted area, which is typically about 60% of the total area 48 .…”

“…A promising approach to intensifying heat integration within an absorption column is the use of 3D‐printed packings capable of removing heat from the column and transfering it directly into a cooling fluid flowing within the packing itself (see Figure 2). Such packings were recently manufactured by Miramontes et al, 28,29 who tested their performance in a bench‐scale column. Their design was a modified version of the Mellapak 250Y structured packing which contained channels in the packing wall through which a cooling fluid could flow.…”
