A rapidly growing number of ships are being fitted with exhaust gas cleaning systems, or "scrubbers," as a way to comply with the International Maritime Organization's (IMO) 2020 global fuel sulfur limit. Scrubbers remove sulfur from ship exhaust by spraying a buffer solution, usually seawater, over it and then discharging the washwater overboard, often without treatment.

Marine scrubbers or vapor cleaning Systems are used to control or eliminate particulate matter and harmful components, such as Sulphur oxides (SOx) and Nitrogen oxides (NOx) from the gases generated from combustion processes of marine engines.; These scrubber system has been developed to scrub exhaust from engines, auxiliary engines, onshore, boilers and onboard marine vessels, to confirm that ...

The MARPOL convention allows for the use of Exhaust Gas Cleaning Systems[1] (EGCS, more commonly referred to as scrubbers) as an alternative means of complying with the 2020 low sulphur regulations. However some jurisdictions have imposed local regulations which restrict or prohibit the discharge of wash water from scrubbers within their waters.

The scrubber itself (dissolution of system materials, possible reaction products and/or chemical additives). The use of scrubbers to clean the exhaust from marine engines using high sulfur residual oil and diesel fuels may lead to high concentrations of a number of harmful compounds in the water body around the ships (AEA, 2009).

• The scrubber pump should be started well before arrival at the discharge berth. • Ensure the scrubber system is functioning correctly and efficiently. • Clear, precise and repeat back communication amongst involved personnel is a key to safer marine operations and ensures a fuller understanding of intentions and plans of action.

Wet Scrubbers: The Importance of Proper Use and Maintenance. Wet scrubbers play a crucial role in the safe discharge of exhaust emissions from industrial workshops, laboratories and manufacturing facilities by removing particles and harmful gases from the discharged air-stream, they help keep workers, the premises and the surrounding environment safe from contaminants.

retract the lower spout discharge. The spout vertical travel is sized to reach the lowest hatch of a railcar or vessel. Dust and displaced air are withdrawn through the annular area between the product column and the Rhinoflex™Flexible Outer Spout, out through the flanged dust outlet and to a dust collector or scrubber.

Fig. 1 shows a picture of the plant and Fig. 2 its P&ID diagram. It consists mainly of the following components: a blower, the conical spouted bed reactor, the biomass feeding system, the gas preheater, equipment for cleaning the gaseous product stream (2 cyclones), the bio-oil condensation and retention system (scrubber, demister and coalescence filters) and a flare to burn the gas purge.

No, I don't want no scrubbers. Elissama Menezes August 9, 2019. A scrubber on a ship leaves harmful discharge out at sea. As the shipping season opens in the north and vessel traffic increases along Canada's coastline, TLC's famous 90's song, "No scrubs" resonates very well with current environmental issues caused by scrubbers.

The discharge of scrubber effluents into the sea carries a number of potential risks to the ecosystem. These include the reduction of the pH value, the increase in the chemical oxygen demand (COD) due to oxidation of sulfites carried by the effluent, temporary temperature rise, increased turbidity, and discharge of other pollutants such as ...
