Abstract: A device for using carbon dioxide originating from the combustion of a byproduct has a preparing unit which is connected to a delivery station for fossil fuels, which has a burner for combusting a byproduct that is released when the fuel is delivered, and an exhaust gas line that is connected to the burner. A depositing device is fluidically connected to the preparing unit via the exhaust gas line, for carbon dioxide. The depositing device is fluidically connected to the delivery station to redeliver fuel via a supply line for carbon dioxide. Such a device allows the production and the subsequent controlled use of carbon dioxide from previously unused byproducts in the production of crude oil. A corresponding method by which carbon dioxide originating from the combustion of a byproduct is used in a controlled manner, in particular as part of a fossil fuel extraction process.

Abstract: A separation apparatus for carbon dioxide is provided which includes an absorption unit for absorbing flue gas from a fossil-fueled power station, a desorption unit and a heat exchanger which on the primary feed side is connected via an inlet-side feedback line to the desorption unit, and on the discharge side is connected via an outlet-side feedback line to the absorption unit. On the secondary feed side, the heat exchanger is connected via an inlet-side feed line to the absorption unit, and on the discharge side is connected via an outlet-side feed line to the desorption unit. A first bypass line connects the inlet-side feedback line to the outlet-side feed line so that a mostly closed first circuit with the desorption unit is formed, and a second bypass line connects the inlet-side feed line to the outlet-side feedback line so a mostly closed second circuit with the absorption unit is formed.

Abstract: A device for separating CO2 from an exhaust gas flow of a combustion device is provided. The device has a store for storing a heat transfer fluid together with a CO2 separating device which has an absorber and a desorber. The store and the desorber are thermally coupled to each other via a line system, and the store is thermally coupled to an electrically driven heating device which allows a thermal conditioning of the heat transfer fluid in the store. The heating device is designed as a gas turbine driven by a generator as a motor, and air is sucked into the compression stage of the gas turbine while the turbine is driven and is substantially adiabatically heated as a result of the compression. The heated exhaust gas exiting the gas turbine interacts with the store for the purpose of the heat transfer.

The carbon dioxide separation device is connected via a process steam line to an intermediate superheating line. Further, an auxiliary condenser is connected to the carbon dioxide separation device. On failure or deliberate switching off of the carbon dioxide separation device surplus process steam is condensed in the auxiliary condenser.
