The invention relates to a method and a device for separating carbon dioxide (CO2) from stack, sludge, and/or exhaust gases. The invention is based on the object of developing a method and a device for separating CO2 from stack, sludge, and/or exhaust gases that can be carried out in a rapid, efficient, energy-saving, and environmentally friendly manner. Accordingly, the method according to the invention for separating carbon dioxide from stack, sludge, and/or exhaust gases by means of absorption and subsequent desorption from an absorption agent characterized in that the absorption agent enriched with CO2 is subjected to an ultrasonic treatment at a temperature below 80°C, preferably between 40 and 79°C, following the absorption of CO2. The device according to the invention for separating carbon dioxide from stack, sludge, and/or exhaust gases by means of an absorption and a subsequent desorption from an absorption agent comprises an absorber (10) for transferring the CO2 of the waste, sludge, and/or exhaust gases into the absorption agent, and a desorber (30) for a subsequent desorption of the CO2, wherein the desorber (30) has an ultrasonic source (31), which is disposed such that the emitted sound energy of the ultrasonic source (31) acts upon the absorption agent being enriched with CO2 such that CO2 is desorbed at a temperature below 80°C, preferably between 40 and 79°C. |
