Abstract
While designing the systems of air regeneration the process like CO2 absorption andoxygen regeneration are the main issues. The paper investigates the efficiency of the packed beds in absorption processes of packed scrubber. The following polypropylene packed beds are used: rings of 140 mm diameter, 5 mm thickness, and 35 mm height; rings of 55 mm diameter, 5 mm thickness, and 60 mm height; and MATALA SM 150 material. Different ways of capping have been used for scrubber working site: in bulk and in layers. For every type of packed bed CO2 concentration, as well as the concentration and flow rate of the absorbent (NaOH), are changed while supplying into the scrubber. The experimental data have been analyzed and compared with the data for packless scrubber. The packed beds have been evaluated in terms of their CO2 absorptionefficiency. The packed bed of combined type using MATALA polymeric material with regular layers of the material and the layers with chaotic filling from the pieces of the same material of the size not more than 100×100×40 mm should be considered as the most effective one. The results obtained allows formulating practical recommendations for designers of air regeneration systems for hermetically closed rooms.
