ABB SCR Converter: Cutting down total emissions from the funnel

The ABB SRC converter is designed for both newbuild and retrofitting of marine diesel engines. It effectively deals with nitrogen oxides (NOx), carbon monoxide (CO) and unburned hydrocarbons. These pollutants are converted into nitrogen and water vapour. The converter allows the diesel engine to operate a maximum efficiency and therefore does not compromise fuel economy with clean emissions. It also significantly reduces NOx emissions from the funnel. It replaces the silencer and takes up no more space than a conventional exhaust system. A monitoring and control system allows emissions levels to be adjusted to meet differing requirements. The first unit was installed in 1992, and Operational-1.c experience has proven units to perform well and reliably. Principles of operation and performance are examined.
