5 WHAT are MARINE SCRUBBERS? An effective and IMO-approved SOx abatment devices that uses alkaline water (such as seawater) to get harmfull SO2 into harmless SO4. Added benefits... Acid rains prevention Particulate Removal 5

6 Shipping accounts for the 6% of the Global SOx emissions shipping land based 94% 6% 6

7 IMO and EU directives impose use of light fuel for shipping since 2015 MARINE SCRUBBERS BUSINESS DRIVERS Price differential Heavy and light fuel will be higher than 250$ in 2020?? Light fuels for the global demand?? LNG viable for retrofit applications?? / Copyright 2015 E. I. du Pont de Nemours and Company. All rights reserved.

8 LNG vs SCRUBBERS for RETROFIT APPLICATIONS Install LNG system Install Scrubber system PROS ü No effluent water management ü Low ship stability impact ü No cargo space loss ü Mature technology ü Fuel availability ü Great fuel cost saving CONS ü Inevitable cargo space loss ü Weak distribu/on network ü Installa/on costs much higher ü Greater engineering ac/vi/es (safety) ü Exis/ng ships are not requested to adress Nox ü Effluent water management ü Power demand increase 8

9 Essential components of a scrubbing system 1. A SOURCE OF WATER (SEAWATER, FRESH WATER + REAGENT) 2. CENTRIFUGAL PUMP(S) 3. SCRUBBING TOWER 4. TREATMENT PLANT FOR THE WASH WATER (mostly mechanical) 5. MONITORING SYSTEM (AIR AND WATER PARAMETERS) 9

10 Tower Design configurations SINGLE-STREAM MULTI-STREAM ü Less ductwork modifications ü Optimized for each source ü Multi funnels configuration ü Cruise & Ferry ü Designed to suit the real ship load profile ü Need isolation valves ü Single funnel configur. ü Cargo ships ü Low CAPEX ü High CAPEX ONE SOURCE, ONE TOWER MULTIPLE SOURCES, ONE TOWER 10

11 Typical operating modes OPEN LOOP Simple design, few auxiliaries, no chemicals Pure Sea water operation, continuous discharge to sea CLOSED LOOP Not subject to alkalinity/water temperature variation HYBRID LOOP Zero discharge option Most flexible solution Lowest OPEX Lowest CAPEX Highest CAPEX Water treatment before discharge (high flow rate) Utilize sea water alkalinity to control ph. Water treatment before discharge (very low flow rate) Utilize base reagent to control ph. Operability in Open or Closed Loop, depending on location Combination of Open + Closed Loop design & benefits 11

12 DuPont TM Marine Scrubbers key design features ü Slim, customizable and designed on specific ship type ü Low pressure drop, not exceeding 100 mm.w.c ü Run dry mode, exhaust gases through the tower outside ECAs ü Engineered in USA and fabricated at qualified workshops next to the shipyards ü Flexible scope of supply, including turn key solutions 12
