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.
