摘要： A process for removing impurities, in particular oxides of sulphur (SOx) and/or oxides of nitrogen (NOx) from oxygen-containing gas streams by scrubbing with at least one washing agent is described. In order to achieve effective gas purification in an economical manner even in the case of so-called large “oxyfuel” furnaces which operate with oxygen as fuel gas, it is proposed to convert the impurities at an elevated pressure of at least 2 bar with at least one basic constituent of the washing agent into salts and to wash out said impurities as dissolved salts.

摘要： The invention relates to a process and an apparatus for the treatment of a carbon dioxide-containing gas stream from a large-scale combustion plant, in particular of a power station. The gas stream is separated in a carbon dioxide purification stage R into a gas substream having an increased carbon dioxide content and a gas substream having a reduced carbon dioxide content. The gas substream having an increased carbon dioxide content is fed to a further use and/or storage S. In particular, compression of the carbon dioxide under the ground can reduce the emission of gases which affect the climate. To increase the proportion of compressible CO2, it is proposed that the gas substream having a reduced carbon dioxide content is fed to a pressure swing adsorption stage PSA in which a fraction which is rich in carbon dioxide and a fraction which is low in carbon dioxide are produced. The fraction which is rich in carbon dioxide is recirculated to the carbon dioxide purification stage R or is passed directly to further use and/or storage S.

摘要： A process and a device for treating a carbon dioxide-containing flue gas stream are described. At least a part of the carbon dioxide present is removed from the flue gas stream by means of a scrubber, forming a low carbon dioxide gas stream and a high carbon dioxide gas stream. The high carbon dioxide and water-saturated gas stream formed from the flue gas stream after removal of the carbon dioxide is cooled by means of a refrigeration system 4 in a heat exchanger 3 below the dew point temperature of the water contained in the gas stream and dried by condensing and separating out the water in a condensate separator 5. The dried gas stream meets the requirements of carbon dioxide products intended for further use.

摘要： A process and an apparatus for the treatment of a carbon dioxide-containing flue gas stream are described, at least part of the carbon dioxide present being removed from the flue gas stream in a separating device having in particular an absorption column 7 with the formation of a gas stream having a low carbon dioxide content and a carbon dioxide-rich gas stream. For overcoming the pressure drop caused by the carbon dioxide removal in the absorption column 7, it is proposed that the gas stream having a low carbon dioxide content and formed after the removal of the carbon dioxide from the flue gas stream is subjected to a gas stream compression, for example by means of a flue gas blower 14.

摘要： A method and a device for purifying a carbon-dioxide-containing gas stream are described, in which the gas stream is first subjected in a lower section (3) of an absorption column (1) to a prescrubbing for conditioning the gas stream and subsequently in an upper section (8) of the absorption column (1) the carbon dioxide is scrubbed out from the gas stream at least in part with a scrubbing liquid. For improving the construction of the absorption column it is proposed that the entire scrubbing liquid loaded with the carbon dioxide which is scrubbed out is taken off from the absorption column (1) and fed to a receiver tank (11) arranged outside the absorption column (1) and subsequently applied to a scrubbing liquid pump (12) which pumps the scrubbing liquid to a scrubbing medium regeneration stage.
