We all see the effects of global warming through different incidents, even in our daily life. Each incident we see or each natural disaster we experience is an emergency call from mother earth. There might be a life cycle for earth just like everything else but there is no doubt that us humans are accelerating the process. With the dramatic increase in growth rate of population has led to some certain consequences which was almost impossible to prevent due lack of know-how at that time. By the development of new enhanced Technologies, humankind has been able to detect the both direct and side effects of the defect in nature.

The IMO and stakeholders of the global maritime industry were among the very first parties whom answered the call for help of mother earth, by taking a set of strict precautions and setting serious regulations repeatedly. As regulations become effective one by one, the maritime industry started to get to know some new applications and technologies. Scrubbers are among these major precautions that is being applied nowadays.

Scrubbers are mainly used for removing particulate matter and harmful components, such as sulphur oxides (SOx) and nitrogen oxides (NOx) from the exhaust gasses generated as a result of combustion process in internal combustion engines, in order to accomplish pollution control and prevent further damages.

These scrubbing systems have been developed and implemented to treat exhaust gases from engines, auxiliary engines onshore and onboard marine vessels, to ensure that no damage is done to human life and the nature of the ecosystem by toxic combustion residues. The main principle of these systems in the most basic words is to ‘wash’ the exhaust gases via scrubber towers by directing the exhaust gas into these towers. A special solvent is sprayed while the gas is passing through and the particulate matter which trapped by the solvent will fall by the help of gravity. So that the toxic component will not be released in to atmosphere.

Installing a scrubber system is one of the key options to meet the new sulphur requirements. Scrubbers are generally considered to be a cost effective way to adapt the current global fleet to SOx emission requirements rather than renewing the whole Main Engine System or building a brand-new vessel.

As we mentioned above, the International Maritime Organization (IMO) is taking into force increasingly stringent emissions regulations to meet the environmental goals. The next level of IMO Sulphur reductions has become effective on January 1, 2020 according to MARPOL Treaty, and the global Sulphur cap has lowered from 3.5 to 0.5%. The consequences of this move will be felt not only at coastal areas but globally by our kids and grandchildren.

It is scrubber today, and may be a more enhanced system tomorrow, but with the help of new technologies we will keep working for greening your world for the upcoming generations.
