What levels of pollutants can a typical wet exhaust gas cleaning system remove from an exhaust stream?
Typical figures for pollutant removal are
SO2 ~ 98%
Particulate Matter ~80%
NOx ~ 5%*
* By water scrubbing.
(Note: Selective Catalytic Reduction (SCR) and Exhaust Gas Recirculation (EGR) can reduce NOx by >80%, enabling IMO Tier III levels to be met)
