Due to strict solid fuel requirements, removal or reduction of chlorine compounds is essential to
reduce the possibility of clogging, corrosion and dioxin formation in cement producing line.
Unfortunately according to Table 2, the total chlorine content of raw MSW was as much as
1.63% or 16,300ppm, with majority (13,800ppm) organic or water-insoluble. Therefore, simple
chlorine reduction by water washing would be difficult to perform, and the product would not be
qualified as solid fuel.
Hydrothermal treatment, however, has the dehydrochlorination effect for PVC9, 10. It can be seen
from Table 3 that the organic chlorine content of the hydrothermal treatment products were low
