CO2 capture in a spray column using different atomization techniques
 Klíma, Petr ; Bělka, Miloslav (referee) ; Malý, Milan (advisor)
Carbon dioxide capture (CO2) can be a key step in the fight against global climate change. One of the promising tehcnologies for CO2 capture is the spray column. This diploma thesis investigated its potential through a review of available literature and laboratory experiments. Specifically, the work included an overview of absorbents and nozzles. Furthermore, research was conducted on the geometric and operational parameters of spray columns and other similar devices used for CO2 absorption and desorption. These findings led to the construction of a spray column and the execution of experiments. The effect of the type of nozzle used, as well as the effect of CO2 concentration in the supplied gas, the effect of atomization pressure and the effect of temperature on the absorption efficiency in the spray column were investigated. Regeneration experiments were also carried out in a spray column and then on a smaller scale in a steel cylindrical vessel.

Design and verification of lab-scale spray column for CO2 capture
 Veselý, Filip ; Bělka, Miloslav (referee) ; Malý, Milan (advisor)
The concept and design of the lab-scaled spray column for CO2 capture which is capable of using optical measurement technologies and provides variations of experimental conditions is crucial to research CO2 absorption using sprays. This thesis is focused on the design of the column and all necessary components. Furthermore, there are discussed experimental conditions and measurement technologies. It provides deep look at velocity profile adjustments and efficiency of the absorption for MEA and aqueous ammonia. There is a discussion about each configuration and its results including design adjustments suggestions.
