Open loop scrubbers

Instead of being re-used, the process water is discharged directly back to sea while complying fully to the IMO regulations. Optionally the seawater can be pumped through a water treatment system to remove all solids and oil. Detailed information can be found in our brochure. Download here.

How does it work?

  • The seawater (process water) is NOT re-circulated but discharged back to sea.
  • The sulphur in the exhaust gases dissolves in the process water.
  • The process water is pumped through a water treatment system and discharged back to sea.
  • Solids and oil from the process water are led to the separator.
  • This separator will separate solids and oil from the process water.
  • The remaining sludge is pumped to the sludge storage tank on the ship.
  • The process water removed from solids and oil will be discharged back to sea.
  • The pH, turbidity and concentration of PAH are constantly measured in accordance with MARPOL Annex VI resolution MEPC.184 (59).
  • The clean exhaust gases exit the scrubber, removed from sulphur and particles, through a demister.

Testimonial

“We were intrigued by the simplicity of the AEC scrubbing system. Their technology works without filters. There is no pollution on the deck, no filters to clean and no maintenance. After testing the AEC closed loop scrubber on the Schleswig-Holstein we were so convinced, we orders scrubbing systems for three more vessels.”

Fini Alsted Hansen, Technical Superintendent Fleet Management at Scandlines.
