On the project
The project will study the mechanisms that take place in the rotational absorber (RPB). It is a combination of mechanisms of liquid spray in the eye, in the rotating packing and in the outer cavity, incl. spray on the outer surface and the formation of a liquid film and mechanisms of mass transfer and absorption of gas. So far, attention has been mostly paid to the effect of rotation, centrifugal force or type of packing on the overall efficiency of gas capture, often supplemented by CFD. There is no relevant literature that illuminates the above-mentioned mechanisms in context, and which studies in detail the interaction between the sprayed liquid and the efficiency of gases capture. E.g. it is stated that 8 to 30% of the capture takes place in the outer cavity, but there is a lack of well-founded data on why and under what conditions this happens. The combination of two teams, where there are experts on the atomization of liquids on the Czech side and experts on RPB and the process side, will enable fundamental progress in understanding the mechanisms of RPB.
