FWE and SCR

There are currently approximately 100,000 seagoing vessels operating on the world’s seas, of which around 8% are cruise ships. Heavy fuel oil is usually used here, the waste product of oil refining with countless highly toxic components, such as heavy metals, sulphur, fibres and other pollutants that have an extremely negative effect on health and the environment.

The extreme sulphur content (up to 4.5% is permitted) of the reasonably priced fuel in particular would destroy any catalytic coated particulate filter system very quickly. Considerable reductions to the permissible sulphur contents are planned gradually for the next eight years; in parts of the North Sea and the Baltic Sea or the Californian Pacific coast, it is only permissible to use what are referred to as light heavy oils, with a sulphur content of under 1%. These reductions are, however, by far not enough to enable catalyst particulate filter systems to be used without problems.

SCR systems for nitrogen oxide reduction can, however, be used today. The Fuel Water Emulsion technology for effective and often even fuel consumption-reducing reduction of the soot and nitrogen oxides can also be used – and this is even independent of the sulphur content in the fuel.

The combination of Fuel Water Emulsion and SCR catalysts can be used for comprehensive soot and nitrogen oxide reduction.
