There are a number of new technologies in the market to reduce the effects of harmful emissions from ships. A scrubber system is one such technology which is used on ships to reduce the pollutants from the ship’s emissions.
Wartsila open loop scrubber system is one such technology which offers low operating costs along with reduced operational impact on the environment.
The Wärtsilä open loop scrubber system is based on the same technology as that used in Wärtsilä Hamworthy’s inert gas systems for more than 50 years. The system operates in an open loop utilizing seawater to remove SOx from the exhaust.
Exhaust gas enters the scrubber and is sprayed with seawater in three different stages. The sulphur oxide in the exhaust reacts with water and forms sulphuric acid. Chemicals are not required since the natural alkalinity of seawater neutralizes the acid.
Wash water from the scrubber is treated and monitored at the inlet and outlet to ensure that it conforms with the MEPC 184(59) discharge criteria. It can then be discharged into the sea with no risk of harm to the environment.
Following the Hamworthy acquisition by Wärtsilä, Hamworthy Seawater Scrubber is renamed Wärtsilä Open Loop Scrubber.
