Equipments for treatment of Marine Pollution

Equipments for treatment of Marine Pollution:

1-oil spill 

Oil spill is release of liquid petroleum hydrocarbon into the sea waters, due to the followings:

·         Sinking or leakage of Oil Carrying Vessels.                        

·         Illegal dumping by Industries.

·         Terrorist activities.

·         Natural Disasters.

Equipment s for removing Oil / chemical spill to reduce Marine Pollution

    A) Floating oil

         To collect the floating oil from the sea surface, many equipment s are used:

·        Sorbent

·        Boom

·        Skimmer

·        Tugs

·        Burning

·        Dispersants

       

        B) Oil mixed with water

              1 - Oily water separator.

              2 - Sweeper boat.

    II - Air emissions from marine vessels 

          

          Emission control technologies can be implemented either as a feature of the original design of the vessel or as a retrofit control device added onto an existing vessel which reduce Marine Pollution.

      Emission control technologies:

       

       1 - In engine modifications.

·      Using side valves in fuel injunction.

·      Exhaust Gas Recirculation (EGR) takes the exhaust gas from the engine and cools and re-routes it back into the engines air intake.  

      2- Water-based controls

           The Humid Air Motor (HAM) uses heated intake air, saturated with water vapor typically produced by the evaporation of seawater, this technology utilizes the heat generated by the engine to produce the temperatures needed to vaporize the seawater.

          

 3. After-treatment on-board controls

·       Selective Catalytic Reduction (SCR).

·        Seawater Scrubbing.

·       Shore-side controls.
