Patent ID: 8337790

Claim:
A system for purification of flue gases from a power plant fired with fossil fuels comprising (a) an absorber having an upper region and a lower region, said absorber comprising an absorber hood, a line for pure gas in the absorber hood, at least one contact installation level comprising at least one spraying level disposed in the upper region wherein an absorber suspension is applied to the at least one contact installation level and raw gas flows through the at least one contact installation level, at least one purification level, at least one droplet precipitator level, an absorption suspension sump disposed in the lower region, and an inflow for raw gas disposed above the absorption suspension sump; (b) a separation device comprising a hydrocyclone; (c) a separate reaction container comprising separate first and second chambers and a partition wall with overflow separating the first and second chambers, a lance disposed in the first chamber for introducing oxidation air into the absorber suspension in the first chamber, and an opening in a lower region of the first chamber for discharging the absorber suspension through a discharge line to the hydrocyclone; (d) a pipeline connecting the absorption suspension sump with the first chamber; (e) an absorption suspension container connected to the second chamber; (f) lines leading from the hydrocyclone to the first chamber and to the absorption suspension container; (g) a gas exhaust hood disposed above the first and second chambers for drawing off exhaust vapors into an exhaust vapor hood; (h) a suspension line for the absorption suspension disposed between the at least one spraying level and the second chamber; and (i) a feed for process water to the at least one purification level disposed above and below the at least one droplet precipitator level and above the at least one installation level.
