MANíS HP SCR FOR TWO-STROKE ENGINES LANDS FIRST REFERENCE

Tuesday, February 26, 2019 

MAN Energy Solutions has announced the first order for its SCR-HP (Selective Catalytic Reduction Ė High Pressure) product.

Mitsui E&S Machinery (MES-M) has ordered three SCR-HP (cluster 3) units in connection with the building of three 87k-dwt bulk carriers. The engines will accordingly meet IMO Tier III emission standards.

Ralph Klaunig, VP, MAN Energy Solutions, said: “The MAN SCR-HP is the market’s most compact system. Regardless, it’s always challenging – and an important milestone – to land a first reference but we expect MAN SCR-HP sales to push on now as a result of this order. Crucially, we are now the only manufacturer capable of delivering both exhaust-gas after-treatment solutions: high-pressure selective catalytic reduction, and exhaust-gas recirculation – including an electrical turbo blower. This allows our two-stroke customers to choose their preferred option as best fits their situation. It is also another step towards a greener future for the shipping industry and global trade as a whole.”

Klaunig continued: “With this engine and turbocharger – both built under license by Mitsui – and the SCR-HP built in-house at our Deggendorf facility, MAN Energy Solutions can rightly call itself a supplier of complete solutions. As an original equipment designer and manufacturer, our product knowledge gives us the greatest competence to develop and fine-tune solutions to our customers’ great benefit.”

MAN Energy Solutions introduced SCR-HP along with licensee, MES-M, in 2017. The development of the new system is based on MAN’s in-house competence with four-stroke engines, for which it can already reference more than 650,000 operating hours.

The MAN SCR-HP is available for two-stroke engines and reduces – through internal catalytic reaction – NOx exhaust emissions to IMO Tier III limits. With specially developed honeycombs and honeycomb materials, as well as an integrated mixing unit, the overall size of the reactor has been drastically reduced compared to typical market designs and its medium-speed counterpart.

The SCR-HP comes in six frame sizes, covering engines up to 25 MW with one reactor for the entire exhaust stream. The SCR-HP system consists of the reactor – including mixing unit, urea injection lance, honeycombs and soot blowers – along with a module-based supply system, as well as the reactor’s control unit that communicates with the engine-control system.
