Scrubbers or Exhaust Gas Cleaning Systems (EGCS) are used to remove particulate matter and harmful components, such as sulphur oxides (SOx) and nitrogen oxides (NOx) from the exhaust gasses generated as a result of combustion processes in marine engines, to implement pollution control.
These scrubbing systems have been developed and employed to treat exhaust from engines, auxiliary engines and boilers, onshore and onboard marine vessels, to ensure that no damage is done to human life and the environment by toxic chemicals.
titanium has a higher up-front installation cost for a marine scrubber compared with Super Austenitic stainless steel (SASS), the increased investment for titanium can be shown to provide a considerably longer service life and a lower [total cost of ownership" based on the aforementioned FGD and seawater environment. unlike specialty stainless steel or nickel alloys, titanium-when properly welded and assembled- maintains an overall corrosion resistance level comparable to the base metal without the requirement for postweld heat treatment.
