Re: Activated carbon stream good for mercury control

Joe,

The carbon injection does work to reduce flue emissions of mercury but only 
by capturing and introducing it to the fly ash. Ellen Connett told me that 
some of the resulting mercury then volatilizes (goes airborne as a gas) from 
the ash because of its finely dispersed condition. Enhanced pollution 
controls aren't really doing the great public health service that people 
assume.

Everything else that controls capture can be found in ash too like dioxins 
etc. This is the biggest reason that using ash isn't such a cool idea. It is 
a huge irony that the EPA  has mandated APC s and ignored the "benificial 
reuse" of ash as a public health threat.
