Ultraviolet and hydrogen peroxide or ozone or ozone and hydrogen peroxide treatment to simultaneously control nitrosamine, nitramine, amine and aldehyde emissions from amine-based carbon capture
Apparatuses for controlling emissions of carbon capture facilities and associated methods are disclosed that generally involve a chamber defining at least one washwater packing. The exemplary apparatuses further include at least one washwater return line, a UV treatment zone and a hydrogen peroxide treatment zone. The UV treatment zone generally receives UV energy sufficient to substantially destroy a first emission compound and the hydrogen peroxide treatment zone generally receives a hydrogen peroxide medium sufficient to substantially oxidize a second emission compound to a less volatile final product. An alternative exemplary apparatus generally involves a UV treatment zone and an ozonation treatment zone, further including a hydrogen peroxide treatment zone applied within the ozonation treatment zone. The exemplary methods generally include applying at least one of a UV treatment, a hydrogen peroxide treatment and an ozonation treatment.
