Selective Catalytic Reduction (SCR) Chemical Principle of NOx Reduction Vaporization of Urea* (NH 2 ) 2 CO in exhaust gas leads Catalytic to formation Reduction of ammonia (NH 3 ) * widely used in agriculture as a nitrogen containing fertilizer; for exact urea specification, please, address to MDT Catalyst < 7 >
Selective Catalytic Reduction (SCR) Main Considerations for CAPEX and OPEX NOx CATALYST CAPEX (for Case Study): MAN SCR Depending on engine type, typically 10% - 15% of engine price OPEX: Backpressure increase by 15mbar to 20mbar ( impact SFOC) UREA consumption for Tier III compliance typically 5% - 7% of fuel consumption, depending on engine load point Price for UREA: 250 USD/t in the past ~ 40% to ~ 80% of HFO price, does not follow oil market < 8 >
SO x Reduction Technology Wet Scrubber Open Loop, Closed Loop, Hybrid System Open loop + Closed loop = HYBRID Type < 9 >
SO x Reduction Technology Main Considerations for CAPEX and OPEX SOx SCRUBBER CAPEX (for Case Study): Hybrid Type 2 systems one per engine room OPEX - Closed Loop: During operation in harbour and manoeuvering SFOC increase by 1.5% (pumps etc.) Backpressure increase by 15mbar Price for Caustic Soda* (50%) : 250 USD/t in the past typically below HFO price Costs for removal of sludge not considered OPEX - Open Loop: During operation at sea SFOC increase by 2.0% (pumps etc.) Backpressure increase by 15mbar * 50% solution in water < 10 >
