Wet lime scrubbing | EMIS

Process description. The wet lime injection process combines the advantages of scrubbers and (semi) dry lime injection. This flue gas cleaning technique is mainly used for desulphurisation of flue gases, while other acid-forming components are also bonded. During wet lime injection, a slurry of limestone (CaCO 3) is sprayed into the spray column.
