Abstract
The present technology is generally directed to systems and methods for removing mercury from emissions. More specifically, some embodiments are directed to systems and methods for removing mercury from exhaust gas in a flue gas desulfurization system. In one embodiment, a method of removing mercury from exhaust gas in a flue gas desulfurization system includes inletting the gas into a housing and conditioning an additive. In some embodiments, conditioning the additive comprises hydrating powder-activated carbon. The method further includes introducing the conditioned additive into the housing and capturing mercury from the gas.
Claims21
1-24. (canceled)
A method of removing mercury from exhaust gas in a flue gas desulfurization system, the method comprising:
- inletting the gas into a housing;
- hydrating the additive to increase a moisture content of the additive;
- introducing the additive, with the increased moisture content, into a dry scrubber associated with the housing;
- and
- capturing mercury from the gas.
The method of claim 1 wherein introducing the additive comprises introducing the additive continuously or at a pre-set timing interval.
A method of removing mercury from exhaust gas in a flue gas desulfurization system, the method, comprising:
- hydrating an additive to increase a moisture content of the additive;
- introducing the additive to emissions within a housing;
- passing the emissions to a baghouse, the baghouse having fly ash therein;
- and
- the increased moisture content of the additive controlling a moisture content of the fly ash in the baghouse in response to the introducing;
- and
- capturing mercury from the emissions.
A method, comprising:
- introducing a hydrophilic additive to emissions within a bag house;
- the bag house having fly ash therein.
