    Closed loop scrubbers

     

    The closed loop is the most frequently used system. The seawater used in the process is continuously re-circulated. Detailed information can be found in our brochure.

    How does it work?

  • From the bottom of the scrubber exhaust gases are led through the scrubber to the top.
  • The seawater is fed into the top of the scrubber through nozzles. This results in an equally divided spray.
  • The outgoing exhaust gases are washed with seawater in the scrubber.
  • The seawater (process water) is continuously re-circulated.
  • The sulphur in the exhaust gases dissolves in the process water pumped from a circulation tank and binds with the caustic soda (NaOH) as a salt.
  • Based on conductivity level a certain amount of process water is drained out of the system automatically.
  • If needed clean seawater is then added to the process water tank and also NaOH, if needed.
  • The process water will be cleaned by the water treatment unit.
  • The remaining sludge is pumped to the sludge storage tank on the ship.
  • The process water with high conductivity level will be discharged directly back to sea while complying fully to the IMO regulations.
  • 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 particulates, through a demister.
  • closed loop scrubbers

    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.

    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 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.
  • open loop scrubbers

    Hybrid scrubbers

     

    The hybrid scrubber system can run in both closed or open loop mode. Water is either re-circulated or discharged back to sea.

    Scrubber wash water treatment system

     

    Damen Green Solutions’ latest development is a one step scrubber wash water aftertreatment solution that ensures a better, safer environment.

    Several countries have already banned open-loop systems discharging wash water in their ports. Vessel operators are being advised to switch to close-loop operation. With this unique aftertreatment system a simple integrated solution ensures both compliance in those regions and a cleaner environment.

    This filter solution collects inlet water from the scrubber wash water collection tank. The filter can handle any wash water in one step and creates dry sludge with up to 85% dry content and clean effluent water in accordance with descriptions given in MEPC 259(68).

    The system is easy to operate and needs no difficult chemical injections. The system is also designed for easy mainteance.

    The system can be designed as a skidded solution or as a modular system.

  • Available in single or dual filterpress system
  • Simple integration with clients scrubber system
  • One step technology
  • Easy to operate
  • Low power consumption
  • Dry solids up to 85%
  • No chemical treatment

    Retrofit projects for scrubbers will have an impact on the existing vessel. Quite some systems need to be installed and commissioned.

    The owner will always decide at which place in the world such a retrofit project will be executed. Damen simply will, in close cooperation with the owner, offer such installation work at that place. This can be reached by forwarding the required material package to this particular county/yard together with a Supervisor. This Damen Supervisor can work together with the local yard management/personnel to execute the scrubber installation work.
