Abstract
A novel, developed active absorbent called Scansorb was tested on three Danish municipal waste incinerators. There is a demand among smaller and medium-sized waste incineration plants for finding a process for flue-gas cleaning with low investment costs. Dry injection processes are frequently the cheapest solution for these plants, but the consumption of hydrated lime is large, and thus expensive. By using an absorbent with a better absorption efficiency than normal hydrated lime, the lime consumption and expenses in form of a.o. disposal fees decrease. Dry injection can either take place by only injecting absorbent in the flue gas duct and later separation in a filter, or by injection into a reactor with a downstream filter. Due to the high reactivity of the active absorbent an investment in a reactor is not necessary, as the absorbent can be blown directly into the flue gas duct. The average concentration of HCl before the flue gas cleaning is approx. 800 mg/Nm{sup 3}/t, the emission requirement 100 mg/Nm{sup 3} t at 10% O{sub 2}. Consumption figures have been found at the three plants by observing this requirement corresponding to 87.5% absorption of HCl. The consumption of Scansorb was reduced essentially in comparison with the
