Nitrogen oxides that cause pollution of the environment are converted to nitrogen and water by adding a reducing agent (urea solution or ammonia). With the SCR process the reducing agent is injected at comparatively low temperatures and the nitrogen oxides are reduced to molecular nitrogen using a catalyst. With the SNCR process the reducing agent is injected directly into the hot flue gas at ...

Depending on the dust concentration of the flue gas a cyclone is installed for pre-dedusting (optional). Lime slurry from the bottom of the scrubber is atomized into the spray absorber by nozzles. The lime reacts with the acid flue gas pollutants SO2, HF and HCl. For the removal of the dust and the dry reaction products a deduster MULTIWIR is used. After dedusting, the flue gas is saturated ...

Liquid carbon dioxide is taken from a tank, completely evaporated in the evaporator and fed to the point of use. In order to ensure safe defrosting of the evaporator, two units connected are operated in parallel. The units are switched over at specific intervals using a time switch. While one unit is in operation, the other one is being defrosted. The only energy consumption of this evaporator at ...
