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.
Claims20
A method of removing mercury from exhaust gas in a flue gas desulfurization system, the method comprising:
- inletting the gas into a housing;
- conditioning powder activated carbon by hydrating the powder activated carbon and increasing a moisture content of the powder activated carbon;
- introducing the conditioned powder activated carbon, with the increased moisture content, into a dry scrubber associated with the housing;
- and
- capturing mercury from the gas.
A method of removing mercury from exhaust gas in a flue gas desulfurization system, the method, comprising:
- conditioning powder activated carbon by hydrating the powder activated carbon and increasing a moisture content of the powder activated carbon;
- introducing the conditioned powder activated carbon to emissions within a housing;
- passing the emissions to a baghouse, the baghouse having fly ash therein;
- and
- the increased moisture content of the powder activated carbon controlling a moisture content of the fly ash in the baghouse in response to the introducing;
- and
- capturing mercury from the emissions.
A flue gas desulfurization system, comprising:
- a source of emissions, the emissions including mercury;
- a housing comprising an inlet in communication with the source, and an outlet in communication with a baghouse;
- a source of conditioned powder activated carbon;
- wherein the powder activated carbon is conditioned by increasing a moisture content of the powder activated carbon;
- and
- an introducer configured to introduce the conditioned powder activated carbon, with the increased moisture content, to a dry scrubber associated with the housing.
