SOx Scrubbing

 Scrubbers are robust and effective Sox abetment devices to be used for the main engines, but also for the auxiliary engines and the boilers, using water as a medium for sulphur absorption. In the end of the day, we wash the exhaust gases. Also, as a side effect, scrubbers provide the particulate removal mainly in mass and not in number.

Components Of Scrubbers

There are five basic components for the scrubber systems.

  • For sure, a source of water, sea water or fresh water, plus a reagent.
  • Then, we need pumps, to give a specific pressure for the spray nozzles and also because the scrubber are placed in the higher level of the ship from the base line
  • Then, we have the scrubber tower, where we can recognize three different sections. The quench section, where we lower the temperature of the gases. The absorber section, where the reaction take place and we absorb the sulphur into the water. And, lastly, the droplet separator, where we separate the water from the exhaust gases so that they can be dry at the stack.
  • Then, we have the treatment plant for the wash water (for the open and the closed loop systems)
  • And most importantly, the monitoring system. The acceptance of exhaust gas cleaning is based on continuous monitoring over air and water parameters.

Parameters Of Scrubbers

The five main design parameters that differentiate the different makers are as follows:

  • The water flow rates. In the end, how many water do we use to scrub exhaust gases?
  • The in line and the by-pass design. With the in line design, we have the quench section at the bottom. Contrary, with the by-pass design, the quench is on the side. In general, the inline design offers a taller, but slimmer solution compared to the by-pass design, which is fatter, but lower in height.
  • We have the water and gases mixing method, the internal design of the tower. Typically there are open spray towers, the packed tower, the cyclonic tower or the oldest plates towers.
  • Now, we have the nozzle design and the spray patterns that increase the gas and liquid contact and increase the absorption efficiency. Different makers have different strategies to do that.
  • Then we have the diameter and the height according to the gas volume that you want to treat. Also, the diameter to settle the internal velocity for the exhaust gases and the height, because of the reaction time needed.
