Incineration mathematical modeling

For purification, particularly ultrapuriflcation, a strong adsorption bond is needed. This means a high Henry s Law constant is needed. The product purity in the fluid effluenf from a fixed bed adsorber depends on fhe Henry s constant, and the purity can be predicted with a mathematical model (Yang, 1987). For ultrapurification, e.g., when impurity levels of parts per billion (ppb) or parts per trillion (ppt) are required, no predictive models exist. This is the case for the removal of dioxins from effluent in incinerators (Yang et al., 1999).

Relatively little work has been published on the mathematical models describing the temperature and concentration profiles in incinerators. Perhaps the most successful approach to date has been that of Essenhigh and coworkers [99, 100], who through suggesting rather simplified models were able to provide an adequate representation of their pilot-scale measurements as illustrated in Fig. 8.33. A somewhat more basic approach was taken by Flanagan [101] and by Szekely [102] but at this time it is questionable whether the quality of the physical information available on these systems would warrant the sophistication and computational labor involved.
