HCl removal characteristics of calcium hydroxide at the dry-type sorbent reaction accelerator using municipal waste incinerator flue gas at a real site

A dry-type reactor was used to reduce the HCl emitted from a municipal waste incinerator. A real-scale reactor was installed downstream of the existing semi-dry reactor (SDR) as part of D local incineration plant, whose HCl removal efficiency was investigated by applying calcium hydroxide (Ca(OH) 2...

Description
Summary:A dry-type reactor was used to reduce the HCl emitted from a municipal waste incinerator. A real-scale reactor was installed downstream of the existing semi-dry reactor (SDR) as part of D local incineration plant, whose HCl removal efficiency was investigated by applying calcium hydroxide (Ca(OH) 2 ). A test dry-type sorbent reaction accelerator (SRx) was designed, and the stoichiometric ratio (SR) of the sorbent and the secondary reaction characteristics of unreacted Ca(OH) 2 in a baghouse were analyzed. For the results, the SRx showed higher HCl removal efficiency and more economic benefits than the other existing flue gas treatment facilities of the incinerator plant. Furthermore, the highest reduction efficiency of HCl was obtained when the differential pressure in the baghouse was maintained at 150mmH 2 O. This is because as the unreacted sorbent attached to the filter surface layer became thicker and the secondary reaction of the HCl removal increased.
