The water-soluble inorganic chlorine content in the product can then be reduced by water
washing and dewatering process. Generally, it can be seen that there are two types of processing:
dry type (short holding period, low steam input) and wet type (long holding period, high steam
input). The wet type process is reducing organic chlorine content in product compared to dry
type process - but requiring more steam.
It can be concluded that high temperature, wet type processing is advantageous only if the
chlorine content is required to be low such as in cement kiln application. Otherwise, to some
extent, dry type processing is adequate to treat MSW for co-firing fuel application
