摘要:
The invention relates to a system for separating volatile degradation products out of a flue gas stream from a load-dependent combustion apparatus (2) comprising a CO 2 separation apparatus (1), wherein the CO 2 separation apparatus (1) has fluidic coupling to the combustion apparatus (2), wherein the CO 2 separation apparatus (1) comprises at least one quench apparatus (4) through which at least part of the flue gas stream flows and which at least partly forms an acidified quench condensate, and an absorber (3) through which at least part of the flue gas stream flows, wherein at least part of the flue gas flows into a cleaning apparatus (23) connected downstream of the absorber (3), wherein the cleaning apparatus (23) is supplied with a cleaning medium for cleaning the flue gas, wherein the cleaning medium at least partly comprises the acidified quench condensate. The invention further relates to a method for operating such a system.

A method is specified for separating carbon dioxide from a flue gas (RG) of an incineration system, wherein bicin (31) and/or EDTA (30) is mixed as an oxidation inhibitor into a scrubbing solution (A) with an amine-containing absorption agent (e.g. 20), the flue gas (RG) is brought into contact with the scrubbing solution (A) prepared in such a manner for absorption of the carbon dioxide contained therein, and the scrubbing solution (A) is then thermally treated, the carbon dioxide being desorbed thereby. A corresponding scrubbing solution (A) comprising an amine-containing absorption agent (e.g. 20) and comprising bicin (31) and/or EDTA (30) as an oxidation inhibitor is also specified.

The invention relates to an absorbent agent, particularly for separating carbon dioxide from the flue gas of a fossil-fired combustion device. The absorbent agent comprises a two-component mixture including a free amino acid and an amino acid salt, wherein the free amino acid exhibits a surplus compared to the amino acid salt based on the molar concentration. This creates variability in the PCBN value, which can be attained through different absorption and desorption process temperatures. The invention furthermore relates to a method for manufacturing the absorbent agent and to a use, particularly for separating carbon dioxide from power plant installations.

The invention relates to a device (30) and a method (1) for work-up of an amino acid salt solution (3), as an absorption agent for carbon dioxide from a flue gas of a combustion process, that has been contaminated with carbon dioxide (2), and comprises a reaction process (100), a subsequent filtration process (200) and a subsequent dissolving process (300). In the reaction process (100), carbon dioxide (2) is introduced into the amino acid salt solution (3), and the amino acid salt solution (3) is cooled. Crystalline carbonate (4) and crystalline amino acid (7) then precipitates out. In the filtration process (200), the crystalline carbonate (4) and the crystalline amino acid (7) are filtered out. In the dissolving process (300), the crystalline carbonate (4) and the crystalline amino acid (7) are dissolved in a solvent (9) and a worked-up amino acid salt solution (15) is thereby obtained.

The invention relates to a method for separating asphaltenes from an asphaltene-containing fuel (3), wherein the fuel (3) is supplied to a separation unit (5) in which a sub-stream (13) comprising low-boiling fuel components (15) of the fuel (3) is separated, wherein after separation of the sub-stream (13) the fuel (3, 19) is supplied to a deasphalting unit (7) in which asphaltenes contained in the fuel (3, 19) are separated by means of a solvent (23), wherein, after the separation of the asphaltenes from the fuel (3, 19), the solvent (23) is separated therefrom in a solvent recovery unit (9), wherein the separated solvent (23) is circulated back into the deasphalting unit (7), and wherein a solvent fraction (39) is obtained from the sub-stream (13) that has been separated from the fuel (3), which is supplied to the deasphalting unit (7) in addition to the solvent (23) recirculated from the solvent recovery unit (9). By means of a method of this type, a process-related solvent loss can be compensated in a simple and cost-effective manner via the targeted treatment of the asphalt-containing fuel. The invention further relates to a device (1, 51, 71) for carrying out a method of this type.

The invention relates to a processing unit (1, 51) for a liquid washing medium contaminated with sulphur oxides and/or nitrogen oxides, comprising an evaporation stage (2, 2) for concentrating the active components of the washing medium by means of an evaporator (3) and/or by means of a heat exchanger (53), and comprising a collecting tank (7) connected to the evaporator (3) and/or to the heat exchanger (53). The invention is characterized in that the collecting tank (7) is configured as a crystallizer (9) for removing sulfur oxides from the washing medium by crystallization of a sulphate, in particular of potassium sulphate. The invention further relates to a separating device (61) for carbon dioxide having a corresponding processing unit (1, 51), and to a method for processing a washing medium contaminated with sulphur oxides and/or nitrogen oxides, wherein a corresponding processing unit (1, 51) is used.
