The invention concerns a separating device for carbon dioxide. The separating device substantially comprises an absorption unit, for taking up flue gas from a fossil-fired power generating plant, a desorption unit and a heat exchanger. The heat exchanger is connected on the primary side in a feeding manner via an inlet-side return line to the desorption unit, and in a discharging manner via an outlet-side return line to the absorption unit. On the secondary side, the heat exchanger is connected in a feeding manner via an inlet-side feed line to the absorption unit and in a discharging manner via an outlet-side feed line to the desorption unit. Furthermore, a first bypass line is provided, by which the inlet-side return line is connected to the outlet-side feed line, so that an at least largely closed first circuit is formed with the desorption unit, and moreover a second bypass line is provided, by which the inlet-side feed line is connected to the outlet-side return line, so that an at least largely closed second circuit is formed with the absorption unit. |
