High-Pressure SCR for Two-Stroke Engines Lands First Order
MAN Energy Solutions has announced the very first order for its SCR-HP (Selective Catalytic Reduction – High Pressure) product. Mitsui (MES) has ordered 3 × SCR-HP (cluster 3) units in connection with the building of three 87k-dwt bulk carriers for the Ocean 21 Holdings company.
Each bulker will be powered by a single MAN B&W 6S46ME-B8.5 low-speed engine delivering 9,900kW at 84rpm, and aspirated by an MAN TCA66 turbocharger. The engines will accordingly meet IMO Tier III emission standards. Delivery dates for the three SCR-HP packages are set respectively for December 2019, and March and May 2020.
Ralph Klaunig, Vice President, MAN Energy Solutions, said, “The MAN SCR-HP is the market’s most compact system. Regardless, it’s always a challenge – 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.”
The MAN SCR-HP is available for two-stroke engines of all bore sizes 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.
