18 What is SCR? Selective Catalytic Reduction, is a catalytic technology to reduce NOx emissions in exhaust gasses. Standard technology used in Stationary and Automotive sector NOx is removed over an SCR catalyst installed in a reactor when a reducing agent (ammonia NH3) is added. The result is harmless nitrogen and water. flow NOx + NH 3 SCR reaction: O 2 N H 2 O MAN Diesel & Turbo Ioannis Author Gekas Korean Shipyard Current Seminar topic < 18 < > 18 >

44 MDT position on bypass of Exhaust gas economizer For SCR system operating on <0.1% S fuel, there is little risk for deposits on the economizer. For SCR system operating on high Sulphur fuel, there is a higher risk to form deposits on economizer that are hard to remove. For such system therefore, MDT recommends installation of economizer safety bypass. In general: For both Tier II and Tier III engines, MDT believes that a safety bypass of the exhaust gas boiler to secure unrestricted passage of exhaust gas from the main engine is a suitable countermeasure that can be used in case of exhaust gas boiler failure or boiler/economizer clogging.

Lower O 2 content (replaced by CO 2 ) Higher heat capacity of scavenge air Reduces peak temperature of the combustion and formation of NO x Recirculated exhaust gas is cooled and cleaned in the EGR system.

88 CSIC regulation on methane slip MAN Diesel & Turbo Author - ME-GI Current Users Forum, topic Busan < 56 < > 88 >

89 Considerations when dealing with China We have recently been informed that as of 1 July 2018, methane slip from gas engines will be restricted on inland waterways in China. The g/kwh limit to be enforced is a huge blow to the Otto-cycle engine solutions, as they will have difficulties in meeting this limit. In fact, they may not be able to do so. This shows a trend towards reducing the methane slip instead of NOx emissions, which is different from other areas. The next step could very well be to expand this regulation to cover Chinese waters in general, which would create problems for owners who have chosen an X-DF engine. Owners wanting to establish a good relationship with China should keep this in mind when they select engine technology.
