Separating carbon dioxide from the flue gases of large, stationary emission sources is considered as one of the most promising medium-term processes for global greenhouse gas stabilization. One of the goals of the research project "New absorption media and absorption processes for CO2-sequestration" was to determine the potential of spray scrubbers for CO2 absorption. Thus, this masters thesis was aimed to convert an existing SO2 scrubber into a CO2 spray scrubbing test plant. For that, a desorption unit consisting of a re-boiler tank and a desorption column had to be designed and laid out. In addition, heat transfer units, pumps, piping, measuring devices and automatic control mechanisms had to be planned and installed. The constructed test plant had a maximum gas flow of 160 m3/h and a maximum liquid flow rate of 2 m3/h. It was set up at the Process Engineering Department of the University of Leoben. The main washing liquid used to separate CO2 from the artificial flue gas stream was a 30 w% monoethanolamine - water solution. The first test results showed a separation efficiency of 20 % to 30 % and suggested further increases.
