"Desorber Of A Co2 Flue Gas Scrubber And Method For Cooling The Co2 Fluid Stream Producted Therein"

Abstract: In the case of a desorber with dedicated washing stage (12), which with a dedicated absorber (2) is part of a CO2 scrubber (1) for the flue gas (7) of a power station, more particularly a fossil-fuelled power station, and preferably a coal-fired power station, and in which a C02-containing fluid stream (10) is produced that is cooled to a temperature suitable for its further treatment in a downstream CO2 compression stage, the intention is to provide a solution which allows a reduction in the construction size of the heat exchanger area needed overall for achieving the cooling of the C02-containing fluid stream to a temperature suitable for its further treatment in a downstream CO2 compression stage. This is achieved in that the washing stage (12) dedicated to the desorber (3) has or provides a cooling performance which brings about the out-coupling of the thermal energy necessary overall for achieving the suitable temperature of the CO2-containing fluid stream, and in a wash water circuit (17) with condensate recycling of the washing stage (12) at least one heat exchanger (19) is arranged which is dimensioned at least for approximately achieving the cooling performance.
