Controlling air pollution is viewed as the main challenge of today that needs to be addressed. The specific concern is hazardous since air contaminants emitted from fossil fuel combustion significantly affect human health and detrimentally impact air quality and the overall environment.
That is why the IMO’s regulations were adopted. According to them, all shipowners of open-loop scrubbing systems must abandon waste water discharge. Consequently, they have to change their air treatment device or find an alternative for reducing NOx air pollutants.
To ensure compliance with the IMO’s regulations, there are several ways to address the issue:
- The use of low-sulfur fuel is the easiest way. All ship engines can operate on various fuel oils; nonetheless, their expenses are still significant.
- Gas-fuelled engines have the added benefit of reducing sulfur air pollutants and NOx emissions. Nevertheless, the air treatment technology mentioned requires higher capital investment because of the expensive fuel storage and delivery system.
- Exhaust gas cleaning systems include scrubbing systems. Scrubbers are widely used for air pollution control. Most land-based systems apply dry scrubbers, however wet air scrubbers are considered more efficient.
There are two main types of scrubbers: dry scrubbers and wet scrubbing systems. To remove SOx emissions, dry scrubbers use the method of passing the exhaust stream over calcium hydroxide, finally, forming gypsum that can be used later in numerous applications.
Even though dry scrubbing systems have simple design and installation requirements, they are heavy and require much space. Dry scrubbers produce no wash water. Wet air scrubbers, on the other hand, direct the exhaust gases from oil-fired engines and boilers through seawater or a special solution.
There are three design options for wet scrubbing systems: open-loop, closed-loop, and hybrids. Furthermore, there is no requirement for extra chemicals for seawater in open-loop scrubbers; however, wastewater storage is necessary since the use of open-loop scrubbing systems is prohibited in many nations.
Thus, closed-loop wet air scrubbers are considered to be most advantageous. If you are looking for the best air treatment device to improve air quality, Redwood Technology offers a cutting-edge type of wet scrubber – a Multi-Vortex wet air scrubber.
Redwood technology is a fast-growing vendor of wet air scrubbers. The multi-vortex scrubber can remove gas emissions, dust, vapors, and other pollutants from a gas stream. It is an innovative technology created to save water that makes it more cost-efficient and differs from other types of scrubbers.
