EGR Turbo Compressor

EGR turbo-compressor for reduction of NOx up to 80%

Exhaust Gas Recirculation (EGR) is a method to significantly reduce the formation of Nitrogen Oxides (NOx) in marine diesel engines. By using this technology, vessels are able to meet with the IMO NOx Tier III standard emission limits applying to the North American and United States Caribbean Sea as well as any new Emission Control Areas.

The EGR compressor is a single-stage turbo-compressor with oil lubricated bearings, direct driven with an asynchronous motor and a variable frequency drive. The design features the unique flow optimization mechanism, utilizing inlet guide vanes to optimize efficiency for a given motor rating.
The core compressor features an impeller, milled from a solid, forged piece of duplex stainless steel with an optimal weight/strength ratio. All parts in contact with the medium are made of corrosion resistant steel. The compressor is equipped with a contact free carbon floating ring sealing to ensure that no exhaust gas can escape from the compressor casing.

The EGR turbo-compressor is available in two sizes:

  • EGR-10, range from minimum 1,02 m3/s to maximum 3,60 m3/s
  • EGR-22, range from 1,80 m3/s to maximum 6,33 m3/s

Principle of the EGR system.​

​In the EGR system, after a cooling and cleaning process, part of the exhaust gas is recirculated to the scavenge air receiver. In this way, part of the oxygen in the scavenge air is replaced by CO2 from the combustion process.

This replacement decreases the O2 content and increases the heat capacity of the scavenge air, thus reducing the temperature peak of the combustion and the formation of NOx. The NOx reduction is almost linear to the ratio of recirculated exhaust gas.
